July 27, 1949 – The first flight of the de Havilland Comet. Though we tend to think of the jet engine as a product of WWII, work had begun on the development of the turbojet engine as early as 1921. The first patent for an axial flow turbojet was granted to Frenchman !!!error: Indecipherable SUB-paragraph formatting!!! , though the engine was never built. Work progressed through the 1930s and 1940s, and both Britain and Germany fielded jet-powered fighters by the end of the war. The next logical step was to take the power of the jet engine and apply it to a large passenger airliner.

During the war, the British and Americans decided to split up the development of large, multi-engine aircraft, with the Americans assuming responsibility for transport aircraft, while the British focused on production of heavy bombers. However, that arrangement left the British in the unenviable position of having very little infrastructure or expertise for the production of transport aircraft when the war ended, and many British airliners were simply converted bombers. To address this shortcoming, the British formed the !!!error: Indecipherable SUB-paragraph formatting!!! in 1942 under the direction of !!!error: Indecipherable SUB-paragraph formatting!!! , which was tasked with the development of large, pressurized aircraft that could carry mail and passengers across the Atlantic Ocean. The committee began meeting in early 1943 and, over the next two years, they found that the requirements of the civilian aviation industry called for five different types of aircraft. One of the aircraft, designated the Type IV, would be a 100-seat, jet-powered, pressurized transatlantic mailplane that could carry one !!!error: Indecipherable SUB-paragraph formatting!!! of cargo at a cruising speed of 400 mph nonstop across the Atlantic.

A proposal for such an aircraft was put forward by !!!error: Indecipherable SUB-paragraph formatting!!! , who headed his own aircraft company and had influential government ties. If successful, the new airliner would fill the need for the Type IV aircraft, as well as Type III, a short-range airliner capable of serving multi-hop routes around the British Empire. A contract was awarded to develop the de Havilland Type 106, which later became known as the DH 106, and de Havilland undertook the design of both the airframe and the engines. While initial studies into the design of the Comet included proposals for a radical tailless design, de Havilland eventually settled on a traditional configuration with a straight wing that had a leading edge swept at 20 degrees and a straight tailplane. The engines were housed in the wing roots, and the groundbreaking airliner featured large, square windows for the passengers. The prototype was powered by four !!!error: Indecipherable SUB-paragraph formatting!!! turbojet engines, but those were replaced by more powerful !!!error: Indecipherable SUB-paragraph formatting!!! axial flow jet engines in production models.

After rigorous testing, the first Comet prototype took its maiden flight on July 27, 1949, and the airliner was introduced to the world at the Farnborough Airshow later that year. The Comet entered service with !!!error: Indecipherable SUB-paragraph formatting!!! (BOAC) on May 2, 1952 and was an immediate success, attracting high-profile passengers including the !!!error: Indecipherable SUB-paragraph formatting!!! . However, structural weaknesses around the large windows soon caused a number of fatal in-flight explosive decompressions, and the Comet was pulled from service in 1954 to investigate the cause of the hull losses. The failures were traced to fatigue cracks around the large windows that arose from repeated pressurization and depressurization of the fuselage, so new rounded windows were introduced, along with a strengthened hull. Comets returned to the skies in 1958 and, though the accidents hurt sales, the airliner went on to enjoy a long career, even after it was surpassed by more modern airliners like the !!!error: Indecipherable SUB-paragraph formatting!!! . Continued development of the Comet led to the creation of variants that stretched the airliner and added more seats and more fuel for increased range. And, when it looked like the Comet’s flying days were over, it was further developed into the !!!error: Indecipherable SUB-paragraph formatting!!! maritime patrol and surveillance aircraft. Including the prototypes, a total of 114 Comets were produced, and the last was retired in 1997.

July 28, 1935 – The first flight of the Boeing B-17 Flying Fortress. In the lead up to the Second World War, two schools of thought emerged on how bombers could be used in battle. The first, tactical bombing, was developed to support ground forces in the achievement of a specific objective, such as overcoming a fortified position or destroying a bridge, while the second, strategic bombing, would be carried out by waves of bombers flying over enemy territory in an effort to destroy factories or flatten cities in hopes of destroying the morale of the civilian population. The Germans focused on the former, and honed the combined arms tactics into the Blitzkrieg warfare that was so effective early in the war. England and America, however, adopted the strategic theories of bombing, particularly those of Italian !!!error: Indecipherable SUB-paragraph formatting!!! . Proponents such as !!!error: Indecipherable SUB-paragraph formatting!!! in England and !!!error: Indecipherable SUB-paragraph formatting!!! in America advocated the construction of fleets of heavy bombers based on the belief that “ !!!error: Indecipherable SUB-paragraph formatting!!! .”

YB-17 prototype (US Air Force)

During the 1930s, rapid advances in aircraft design and construction left behind the fabric-covered biplanes of the 1920s in favor of all-metal monoplanes of increasing size, strength and capability. Boeing introduced the US Army Air Corps’ first all-metal bomber with the !!!error: Indecipherable SUB-paragraph formatting!!! in 1931, and Martin followed in 1934 with the !!!error: Indecipherable SUB-paragraph formatting!!! , the first truly modern bomber. But as soon as the B-10 entered service, the USAAC began the search for a new bomber to replace it, one that would be capable of carrying a “useful bomb load” at 10,000 feet, could stay aloft for 10 hours, and have a speed of 200 mph. A competition took place at Wright Field in Ohio between the !!!error: Indecipherable SUB-paragraph formatting!!! , the !!!error: Indecipherable SUB-paragraph formatting!!! , both twin-engine aircraft, and the Boeing Model 299, which had four engines. When the new Boeing bomber, bristling with defensive armament, was first rolled out to the press, a newspaper reporter remarked that the bomber looked like a “flying fortress.” The name stuck.

While USAAC brass were impressed by the performance of the Model 299, now carrying the designation YB-17, they were concerned about the higher cost of the larger bomber. Following the a crash during testing that destroyed the Boeing prototype, the Air Corps chose the Martin bomber. But this was not the end of the B-17. Its performance was impressive enough for the USAAC to order 13 YB-17s for further evaluation, and its performance in testing was so good that by the outbreak of WWII in December of 1941 there were already 155 Flying Fortresses in the air. As the Flying Fortress showed its mettle in combat, those numbers soon soared into the thousands. Following the B-17's first foray into battle in the hands of British pilots, the 8th Air Force alone racked up more than 10,000 missions over Europe. The B-17G variant, which was built in the greatest numbers (over 8,000), had no less than 13 defensive !!!error: Indecipherable SUB-paragraph formatting!!! .50 caliber machine guns and could carry up to 8,000 pounds of bombs depending on the mission. To meet the demand, wartime production of the B-17 was carried out by Boeing, Douglas, and Vega (a subsidiary of Lockheed), and a staggering total of 12,731 Flying Fortresses were produced by the end of the war.

While the bomber didn’t always get through, the Flying Fortress was capable of withstanding an enormous amount of damage while still bringing its crew home. The B-17 became the iconic American bomber of the war in Europe, and teamed up with the !!!error: Indecipherable SUB-paragraph formatting!!! and other smaller bombers to rain 1.4 million tons of bombs on Axis targets, with the B-17 accounting for roughly half that number. As for strategic bombing, !!!error: Indecipherable SUB-paragraph formatting!!! discovered mixed results. While Germany’s production of oil and ammunition was significantly affected, along with the almost total destruction of transportation capabilities and the halt of submarine production, supplies of aircraft actually increased throughout the war, and other supplies, such as ball bearings and steel, were virtually unaffected. Anywhere from 350,000 to 500,000 civilians were !!!error: Indecipherable SUB-paragraph formatting!!! , but bombing itself did not lead directly to German capitulation. Following the war, the vast majority of B-17s were broken up and sold for scrap, though a handful continued to serve in different roles. The Brazilian Air Force retired its last Flying Fortress in 1968, and today only about 14 remain airworthy, none of which are combat veterans.

July 29, 1967 – Fire engulfs the flight deck of USS Forrestal off the coast of Vietnam. Working on the flight deck of an aircraft carrier has been called one of the most dangerous jobs in the world. Controlling jet and propeller aircraft around a pitching deck is an intricate ballet of blasting jet engines and spinning propellers, with death or serious injury a constant concern. And that is just during peacetime. In wartime, the dangers are compounded by a higher tempo of operations and the presence of bombs, missiles, rockets and fully-fueled aircraft either on the flight deck or stored belowdecks. In fact, the !!!error: Indecipherable SUB-paragraph formatting!!! took a critical turn when American dive bombers arrived overhead while Japanese aircraft were sitting on deck, fully loaded with bombs and fuel. The US Navy has been honing the art of carrier operations and carrier safety since 1920, but despite rigid safety procedures, there is always the potential for disaster.

By the early summer of 1967, the war in Vietnam was escalating dramatically, and the carrier !!!error: Indecipherable SUB-paragraph formatting!!! (CVA-59) sailed from Norfolk, Virginia to take up a position at !!!error: Indecipherable SUB-paragraph formatting!!! in the !!!error: Indecipherable SUB-paragraph formatting!!! off the coast of Vietnam. Once there, Forrestal immediately began launching attacks against North Vietnam in support of American and South Vietnamese troops and, as the pace of operations increased, the Navy’s demand for bombs soon outstripped production. To keep the bombers flying, the Navy was forced to use older ordnance, some of which dated back more than 10 years and had been exposed to the elements while in storage. On the day preceding the accident, Forrestal received a shipment of 1000-pound bombs, many of which were older, unstable bombs that had been improperly stored in Guam. Forrestal’s commanding officer, Captain !!!error: Indecipherable SUB-paragraph formatting!!! , at first refused the munitions, but he ended up accepting them reluctantly because of the acute shortage and the need for the bombs on missions the following day. Forrestal’s bomb handlers were particularly concerned with the unstable bombs being stored belowdecks, where an accidental explosion could sink the entire ship. So the bombs were stored out in the open on the flight deck.

The next day, the deck of Forrestal was crammed with fueled and armed aircraft and swarmed with deck handlers, pilots, and other personnel. Shortly before 11:00 am an electrical fault in a 5-inch !!!error: Indecipherable SUB-paragraph formatting!!! caused it to launch unintentionally from a !!!error: Indecipherable SUB-paragraph formatting!!! parked on the flight deck and strike the external fuel tank on an armed !!!error: Indecipherable SUB-paragraph formatting!!! . While the rocket did not explode, it punctured the fuel tank and the leaking fuel ignited. As damage control teams rushed to fight the rapidly spreading fire, one of the unstable bombs loaded on the Skyhawk detonated, blowing a hole in the armored flight deck and raking the deck with shrapnel. Most of the members of Forrestal’s most experienced damage control team were killed, and even more burning fuel was spread around the deck. As the fires continued to rage, nine more explosions occurred, eight of which were caused by the unstable bombs. The detonations tore holes in the flight deck that allowed burning jet fuel to flow into the living quarters below and into the interior spaces of the ship. Without heavy equipment, Forrestal’s crew pushed damaged aircraft into the water and rolled bombs over the side of the ship by hand.

In what Rear Admiral Harvey P. Lanham later called an act of “magnificent seamanship, ” Commander Edwin Burke maneuvered the destroyer !!!error: Indecipherable SUB-paragraph formatting!!! !!!error: Indecipherable SUB-paragraph formatting!!!   (DD-851) to within 20 feet of Forrestal and held station there for 90 minutes in order to use its own fire hoses to fight the fire, and Forrestal’s crew was eventually able to extinguish the fire by 4:00 am the following morning. The fire and explosions, the worst on a US carrier since WWII, claimed the life of 134 crewmen, while 161 were injured, many of them seriously. Forrestal returned to Norfolk, where it spent more than 200 days undergoing repairs and refitting. Though Capt. Beling was absolved of responsibility for the fire, he was assigned to staff work following the incident and retired in 1973 with the rank of Rear Admiral. Forrestal returned to service in the Mediterranean in 1968, and was decommissioned in 1993.

Northrop F-5E Freedom Fighter (US Air Force)

July 30, 1959 – The first flight of the Northrop F-5A Freedom Fighter. When the first jet fighters appeared near the end of WWII, they were relatively simple affairs, essentially straight-winged piston aircraft that were adapted for the new turbojet engines. But as jet engines became more powerful, fighters got bigger, more complex—and more expensive. To combat this trend, Northrop began working on a small, simple fighter in the mid-1950s called the N-156 in the hopes of securing a contract to produce a fighter that could fly from the US Navy’s smaller !!!error: Indecipherable SUB-paragraph formatting!!! . The design team was led by Northrop’s vice president of engineering !!!error: Indecipherable SUB-paragraph formatting!!! , who designed two of arguably the greatest fighters ever built, the !!!error: Indecipherable SUB-paragraph formatting!!! and !!!error: Indecipherable SUB-paragraph formatting!!! , before coming to Northrop. Along with chief engineer Welko Gasich, the Northrop team set out with the specific goal of creating a small, low-cost fighter that would be easy to maintain and easy to fly, but would also have the potential for future growth and development.

Not only were fighters getting larger and larger, but the engines that powered them were also growing in size and complexity. To keep the size of their new fighter at a minimum, Northrop selected two powerful !!!error: Indecipherable SUB-paragraph formatting!!! turbojet engines which had originally been designed to power the !!!error: Indecipherable SUB-paragraph formatting!!! target decoy. Though the J85 was small, weighing in at just 300-500 pounds, it provided 3,500 pounds of thrust in normal operation and 5,000 pounds with afterburner. Combined with the fighter’s small size and use of the !!!error: Indecipherable SUB-paragraph formatting!!! , which gave the F-5 its characteristic slim waist, the F-5 was capable of a top speed of Mach 1.6 with a thrust-to-weight ratio of up to 7.5:1, compared to the !!!error: Indecipherable SUB-paragraph formatting!!! at just 4.7:1. The F-5 was armed with two 20mm !!!error: Indecipherable SUB-paragraph formatting!!! revolver cannons in the nose with 280 rounds each. Seven hardpoints could carry up to 7,000 pounds of bombs, rockets, missiles, or extra fuel tanks.

The changing needs of the US Navy led them to abandon the use of smaller escort carriers, but Northrop forged ahead with their design and developed both a single-seat fighter version, the N-156F, and a two-seat trainer version, the N-156T. In July 1956, the Air Force chose the N-156T to replace the !!!error: Indecipherable SUB-paragraph formatting!!! as its primary trainer, and the newly designated !!!error: Indecipherable SUB-paragraph formatting!!! became both the first supersonic trainer and eventually the most-produced trainer in the world. Northrop continued developing the N-156F in the hopes of providing a fighter for the !!!error: Indecipherable SUB-paragraph formatting!!! , which sought to arm nations allied to the US with low-cost weapons. It was this aircraft which took its maiden flight on July 30, breaking the sound barrier on its first flight. Despite the excellent performance and reliability of the F-5, the Air Force showed little interest in the fighter, and the program was in danger of being shut down. However, the Kennedy Administration chose the F-5 in 1962 as the winner of the F-X completion to provide a low-cost export fighter to America’s allies. In 1965, the Air Force sent 12 F-5As to Vietnam to evaluate them under the codename Project Skoshi Tiger, and it was here that the F-5 received its unofficial nickname, which later became official with the F-5E/F Tiger II.

While the F-5A and F-5E/F weren’t adopted in large numbers by the US, it continues to be flown in the aggressor role for dissimilar combat training, and the Air Force has also bought back some export fighters for use in this role. The Tiger II, which won the International Fighter Aircraft competition in 1970, remains in service alongside older Freedom Fighters the world over. Northrop attempted yet another upgrade to the plucky little fighter with the !!!error: Indecipherable SUB-paragraph formatting!!! , hoping to develop an export fighter that would compete with the !!!error: Indecipherable SUB-paragraph formatting!!! , but it was ultimately unsuccessful. By the end of production in 1987, a total of 847 F-5A/B/C aircraft had been built, along with nearly 1,400 F-5E/Fs.

July 27, 1958 – The death of Claire Chennault. Chennault was born September 6, 1890 in Commerce, Texas and became a pilot during WWI after a stint as a school principal. A proponent of the pursuit fighter in the 1930s at a time when the US Army was focused on bombers, Chennault left the Army in 1937 and worked as an aviation advisor to the Chinese government, becoming the head of the 1st American Volunteer Group, better known as the !!!error: Indecipherable SUB-paragraph formatting!!! , in 1941. Chennault led the AVG and, later, the US Army Air Forces units that followed the disbandment of the AVG, but openly feuded with General !!!error: Indecipherable SUB-paragraph formatting!!! , the US Army commander in China. Stilwell wanted Chennault’s forces to support ground supply routes into China, while Chennault advocated bombing Japanese targets in support of Chinese Nationalist forces. Following the war, Chennault created the !!!error: Indecipherable SUB-paragraph formatting!!! , later known as !!!error: Indecipherable SUB-paragraph formatting!!! , to support the Nationalist fight against Communist China. Chennault died in 1958 at age 64.

July 27, 1947 – The first flight of the Bristol Sycamore, the first domestically designed and built helicopter to serve with the Royal Air Force. Bristol began working on helicopters as early as 1944, and development of the Sycamore took over two years. The prototype was powered by a !!!error: Indecipherable SUB-paragraph formatting!!! 9-cylinder radial engine, though production models were fitted with an !!!error: Indecipherable SUB-paragraph formatting!!! radial engine which provided a top speed of 132 mph. The Sycamore entered service in April 1953 and served during the !!!error: Indecipherable SUB-paragraph formatting!!! , and was also flown by Germany, Belgium and Australia. A total of 180 were built from 1947-1955, and the type was retired in 1972.

July 27, 1946 – The first flight of the Supermarine Attacker, a fighter developed for the Royal Navy’s Fleet Air Arm (FAA) and the first jet fighter to enter operational service with the FAA. The Attacker has its roots in the !!!error: Indecipherable SUB-paragraph formatting!!! , a piston-powered fighter designed to replace the !!!error: Indecipherable SUB-paragraph formatting!!! . The Attacker used the same straight, !!!error: Indecipherable SUB-paragraph formatting!!! wings of the Spiteful and was powered by a single !!!error: Indecipherable SUB-paragraph formatting!!! turbojet which gave it a top speed of 590 mph. Since the wings, with their main landing gear, came from an existing fighter, the Attacker had a tail-dragger arrangement which was unusual for a jet fighter. The Attacker entered service with the FAA in 1951, but developments in jet fighter design quickly rendered it obsolete, and it was withdrawn from service in 1954 after the production of 182 aircraft.

July 27, 1937 – The first flight of the Focke-Wulf Fw 200 Condor, a large four-engine aircraft originally developed by !!!error: Indecipherable SUB-paragraph formatting!!! as a long-range transatlantic airliner. Focke-Wulf’s chief designer !!!error: Indecipherable SUB-paragraph formatting!!! developed the Condor to cruise at nearly 10,000 feet, the limit for an unpressurized airliner. The Condor enjoyed a brief career as an airliner with Deutsche Lufthansa, where it set a record for flying from Berlin to New York City in just under 25 hours. With the outbreak of WWII, Focke-Wulf added a gondola and bomb bay to turn the Condor into a long-range maritime patrol bomber. Later, the Condor was used exclusively by the Luftwaffe as a troop and VIP transport. A total of 276 were produced from 1937-1944.

July 28, 2008 – The death of Margaret Ringenberg. Born in Fort Wayne, Indiana on June 17, 1921, Ringenberg learned to fly in 1941 at age 19 and began her flying career in 1943 as part of the !!!error: Indecipherable SUB-paragraph formatting!!! (WASP), ferrying aircraft, performing test flights, and pulling targets for fighter practice. After the war, Ringenberg took up air racing, eventually earned over 150 trophies, and competed in the Round-the-World Air Race in 1994 at the age of 72. At the time of her death, Ringenberg had amassed more than 40,000 hours of flying time.

July 28, 1945 – A North American B-25 Mitchell crashes into the Empire State Building. During a period of thick fog over New York City, a US Army Air Forces !!!error: Indecipherable SUB-paragraph formatting!!! was performing a routine personnel transport mission when the pilot was instructed to abort his landing and proceed to Newark Airport due to poor visibility. Becoming disoriented in the fog, pilot William Smith crashed into the !!!error: Indecipherable SUB-paragraph formatting!!! between the 78th and 80th floors, killing himself, his two passengers, and 11 civilians inside the skyscraper. Based on this accident, the architects of the !!!error: Indecipherable SUB-paragraph formatting!!! considered the possibility of an accidental impact by a !!!error: Indecipherable SUB-paragraph formatting!!! when they designed the towers, little knowing that such a scenario would play out purposefully in 2001.

July 28, 1914 – World War I begins. World War I was a watershed event in the history of aviation, as the airplane became a weapon of war a mere 11 years after the first flight of the !!!error: Indecipherable SUB-paragraph formatting!!! . Aircraft first entered the fray as observation planes known as scouts, but pilots soon began shooting at each other with small arms. The first dedicated combat aircraft, the !!!error: Indecipherable SUB-paragraph formatting!!! , arrived in early 1915. Technological advances brought ever more powerful and faster fighters, and an interrupter mechanism created by !!!error: Indecipherable SUB-paragraph formatting!!! allowed fighters to fire through the arc of the propeller, thereby dramatically increasing the accuracy and effectiveness of aerial marksmanship. By the end of the war on November 11, 1918, the Germans has lost more than 27,000 aircraft to enemy fire or crashes, while members of the !!!error: Indecipherable SUB-paragraph formatting!!! powers lost more than 88,000. More than 15,000 airmen were lost.

July 29, 1958 – President Dwight Eisenhower signs the National Aeronautics and Space Act, creating NASA. NASA has its origin in the !!!error: Indecipherable SUB-paragraph formatting!!! , an agency created in 1915 to further the efforts of aeronautic research and technological development in the United States. But as America entered the space age following WWII, the country needed an organization for a new era. The !!!error: Indecipherable SUB-paragraph formatting!!! carries this simple preamble: To provide for research into problems of flight within and outside the earth’s atmosphere, and for other purposes. While NASA has done, and continues to do, research that carries military implications, its stated purpose is that of a peaceful, non-military organization. The Act goes on to say that, “The Congress hereby declares that it is the policy of the United States that activities in space should be devoted to peaceful purposes for the benefit of all mankind.” In addition to NASA’s high profile space programs such as !!!error: Indecipherable SUB-paragraph formatting!!! , !!!error: Indecipherable SUB-paragraph formatting!!! , !!!error: Indecipherable SUB-paragraph formatting!!! , the !!!error: Indecipherable SUB-paragraph formatting!!! , and the !!!error: Indecipherable SUB-paragraph formatting!!! , the organization continues to fund research into all aspects of space exploration, space travel, aviation, and related sciences.

Grumman eliminated the wing root air intakes and moved them forward to help reduce drag, made the wing thinner, moved the elevator down to the fuselage, and reshaped the fuselage to take advantage of the newly discovered principle of !!!error: Indecipherable SUB-paragraph formatting!!! . The Tiger remained a work in progress throughout its career, and also earned the dubious distinction of being the first jet to shoot itself down when it overtook its own bullets in a dive during weapons testing. The Tiger’s operational career was relatively short, though it gained notoriety when the fighter was selected by the Navy’s !!!error: Indecipherable SUB-paragraph formatting!!! in 1957. A total of 200 Tigers were produced from 1954-1959, and it was retired from active service in 1961, though it served the Blue Angels until 1969.

So most people know John McCain was caught up in the Forrestal fire (plane 416, the one poking out of all that smoke and fire):

I hadn’t read about his escape until recently though, apparently he had to walk out on his refueling boom and then hop down from there because the flames were so intense (presumably he was already out when the above photo was taken). IIRC correctly, he then dropped off the deck into the netting below and got to safety from there, which seems more difficult than just running across the deck, but maybe if you are worried about those bombs cooking off at any moment, you get to cover as quickly as possible instead of taking to the open deck ?

This took me over to YouTube because I thought it was possible to see McCain climbing out of his jet. I was unable to find that, but I did find a vast collection of conspiracy theorists who say that McCain was responsible for the fire by performing a wet start on his A-4, that he unintentionally (or intentionally) dropped the bombs off his bomb racks as he escaped that led to a greater disaster, and that he then fled the flames and did not try to fight them, leaving others to die in the conflagration that he caused.

I give up.

Yep, there’s some crazies out there, especially people who need to justify Trump. There’s plenty of real reasons out there to dislike the man, but there’s no reason to try to pin this tragedy (where multiple squadmates of his were killed, presumably along with others he know) on him in the complete absence of any plausible evidence .

Clearly, evidence no longer matters when you can simply say, “I don’t believe it and you’re wrong.” It’s really depressing, because I don’t see how we ever come back from this.

Interesting about the Comet, I didn’t know those had a life after the initial disasters.

Yes, it flew quite well after they got the bugs worked out, long after it left its commercial duties. In many ways, though, it was a victim of the rapid pace of development. Once the Dash 80 arrived, the Comet was practically obsolete.
