December 6, 1957 – The first flight of the Lockheed L-188 Electra. Lockheed has a long and rich tradition of building fighters and military transport aircraft, and the mention of the company immediately brings to mind the brilliant !!!error: Indecipherable SUB-paragraph formatting!!! and the graceful, world-spanning !!!error: Indecipherable SUB-paragraph formatting!!! . The Constellation was Lockheed’s most successful large civilian airliner, but the airliners that followed marked a decline of Lockheed in the civilian market which eventually ended with the !!!error: Indecipherable SUB-paragraph formatting!!! and Lockheed’s departure from the civilian airliner market entirely.
A Lockheed L-188 Electra of launch customer American Airlines in 1960
Following the arrival of the jet engine in the closing stages of WWII, airlines began to show interest in turboprop-powered airliners in the 1950s. Lockheed was caught between the competing interests of American Airlines, who wanted accommodation for 75 passengers and a 2,000 mile range, and Eastern Air Lines, who wanted longer range, a cruising speed of 350 mph, and room for up to 90 passengers. Lockheed had originally designed their turboprop-powered CL-310 to meet American’s specifications, but then responded to Eastern’s requirements by lengthening the fuselage and mounting four Allison 501 turboprops, the civilian version of the !!!error: Indecipherable SUB-paragraph formatting!!! . Lockheed fitted enormous propellers to the engines and gave the CL-310 very short wings, which provided the new airliner with performance that rivaled contemporary jet-powered aircraft. Large !!!error: Indecipherable SUB-paragraph formatting!!! also gave the CL-310 excellent performance on short airfields and at airports in higher elevations. The new airliner, now dubbed the L-188 Electra and the last in the line of Lockheed aircraft to bear the name, was the first large turboprop airliner produced in the United States.

The L-188 entered service with Eastern Air Lines in January 1959, but three fatal accidents in the first year of service raised serious doubts about the safety of the new airliner. As a result of the crashes, the Federal Aviation Administration mandated lower speeds for the L-188 while they investigated the accidents. The cause of two of the crashes was traced to problems with the engine mounts, specifically a condition known as “ !!!error: Indecipherable SUB-paragraph formatting!!! ” in the outboard engines which caused oscillations in the wings that eventually led to the wings shearing off from the aircraft. Lockheed was able to fix the problem by modifying the engine mounts and strengthening the wings, but the L-188 was never quite able to overcome the perception that it was a dangerous aircraft.
Coming at the same time as the arrival of the turbojet engine in the civilian airliner market, sales of the L-188 plummeted, and production ended in 1961 after the construction of just 170 aircraft. Lockheed ultimately lost over $100 million on the L-188 in development and modification costs and lawsuits. Though not flown in large numbers, some Electras continued carrying passengers into the 1980s, and many were converted into freighters. And, while Lockheed didn’t find great success with the Electra in the civilian market, the aircraft eventually found a home with the military. In response to a 1957 request for a new maritime surveillance and antisubmarine aircraft to replace the !!!error: Indecipherable SUB-paragraph formatting!!! and !!!error: Indecipherable SUB-paragraph formatting!!! , Lockheed developed the L-188 into the !!!error: Indecipherable SUB-paragraph formatting!!! , and ultimately built nearly four times as many Orions as its civilian counterpart.

December 7, 1941 – Japan launches a sneak attack on US military bases at Pearl Harbor, Hawaii. As part of a strategy to neutralize the American Pacific fleet to facilitate further Japanese conquest in east Asia and the western Pacific, six Japanese aircraft carriers launched a sneak attack on American military facilities at Pearl Harbor, Hawaii. The attack killed 2,403 Americans and, while it was ultimately a strategic failure, it gave American President Franklin Roosevelt the justification he needed to bring the US into World War II.

December 6, 1993 – The first flight of the Bombardier 415, an amphibious water bomber used to fight fires. The 415 is a scooper aircraft, meaning that it can land on the surface of the water, scoop up a planeload of water, then take off and drop it where needed. A development of the !!!error: Indecipherable SUB-paragraph formatting!!! , an earlier radial-engine powered aircraft, the 415 is powered by two turboprop engines and can scoop up to 1,620 US gallons of water at a time. The 415 is known as the Super Scooper, and has entered service in nine countries, with 90 delivered worldwide. Older CL 215 aircraft are also being retrofitted with new turboprop engines as the CL-215T. (Photo by Maarten Visser via !!!error: Indecipherable SUB-paragraph formatting!!! )

December 6, 1991 – The first flight of the Dornier 328, a turboprop commuter airliner originally produced by !!!error: Indecipherable SUB-paragraph formatting!!! and later by Fairchild Dornier after !!!error: Indecipherable SUB-paragraph formatting!!! acquired the company in 1996. The international consortium produces the 328 in Germany, but conducts sales from their offices in San Antonio, Texas. The 328 is powered by two !!!error: Indecipherable SUB-paragraph formatting!!! turboprops and entered service in 1993. It currently flies for small airlines in 15 countries, serves in the military surveillance and search and rescue roles, and is flown by the !!!error: Indecipherable SUB-paragraph formatting!!! as the C-146A Wolfhound. A jet-powered derivative, known as the !!!error: Indecipherable SUB-paragraph formatting!!! , first flew in January 1998.

December 6, 1944 – The first flight of the Heinkel He 162. In 1944, Germany launched a desperate program to develop jet powered fighters to combat the waves of Allied bombers flying over Germany. The !!!error: Indecipherable SUB-paragraph formatting!!! produced a number of prototypes, one of which was the Heinkel 162, named the Volksjäger , or People’s Fighter. Built primarily of wood and powered by a single !!!error: Indecipherable SUB-paragraph formatting!!! axial flow turbojet mounted on the top of the fuselage, the He 162 was the fastest of the early jet designs of the war and found success against both bombers and fighters. However, like most of the German jet fighters, it was a case of too few aircraft coming too late to have a significant effect on the war’s outcome. (Photo via San Diego Air and Space Museum)

December 6, 1928 – North American Aviation is founded.
Though not a pilot or aircraft designer, financier
!!!error: Indecipherable SUB-paragraph formatting!!!
originally founded North American Aviation (NAA) as a holding company to manage interests in various other airlines and aircraft companies, but the
!!!error: Indecipherable SUB-paragraph formatting!!!
forced Keys to make NAA its own manufacturing company. During WWII, NAA became one of the preeminent builders of warplanes, including the iconic
!!!error: Indecipherable SUB-paragraph formatting!!!
, the
!!!error: Indecipherable SUB-paragraph formatting!!!
medium bomber and the
!!!error: Indecipherable SUB-paragraph formatting!!!
trainer. In the 1950s, NAA produced America’s first great swept-wing jet fighter in the
!!!error: Indecipherable SUB-paragraph formatting!!!
, and worked with experimental aircraft such as the
!!!error: Indecipherable SUB-paragraph formatting!!!
and
!!!error: Indecipherable SUB-paragraph formatting!!!
. For the US space program, NAA manufactured the
!!!error: Indecipherable SUB-paragraph formatting!!!
and built the second stage of the
!!!error: Indecipherable SUB-paragraph formatting!!!
rocket. In 1967, NAA merged with Rockwell-Standard to become
!!!error: Indecipherable SUB-paragraph formatting!!!
, which changed its name to Rockwell International the following year, and the company ceased to exist in name following a merger with
!!!error: Indecipherable SUB-paragraph formatting!!!
in 1973.

December 7, 1995 – The Galileo space probe arrives at Jupiter. Galileo was carried into space aboard the !!!error: Indecipherable SUB-paragraph formatting!!! on !!!error: Indecipherable SUB-paragraph formatting!!! which launched on October 18, 1989. The combination orbiter and entry probe was the first spacecraft to orbit Jupiter, and was designed to study the planet along with several other celestial bodies in our Solar System. Galileo’s !!!error: Indecipherable SUB-paragraph formatting!!! was released six months before Galileo reached Jupiter and, during its descent, the probe collected data on cloud composition and measured winds of 190 mph. Galileo made its own observations, finding ammonia clouds on Jupiter, confirming volcanic activity on Jupiter’s moon Io, and finding evidence of liquid oceans on the moon Europa, among others. Since Galileo may have been carrying bacteria from Earth, the spacecraft was intentionally crashed on Jupiter to avoid any possible contamination of Jupiter’s moons. (NASA Illustration)

December 7, 1972 – The launch of Apollo 17, the final mission of the Apollo program. Mission Commander !!!error: Indecipherable SUB-paragraph formatting!!! and Lunar Module pilot !!!error: Indecipherable SUB-paragraph formatting!!! spent just over three days on the lunar surface, performing three moonwalks and covering 22 miles in the !!!error: Indecipherable SUB-paragraph formatting!!! (LRV), which was left behind on the Moon. Astronaut !!!error: Indecipherable SUB-paragraph formatting!!! remained in lunar orbit as the Command Module pilot. Apollo 17 was the first nighttime launch of an Apollo mission, and the last manned launch of the !!!error: Indecipherable SUB-paragraph formatting!!! rocket. Apollo 17 also broke the record for the longest manned lunar flight, the longest total time spent exploring the surface of the Moon, the largest return of Moon samples, and the longest time in lunar orbit. Apollo 17 returned to Earth on December 19, 1972. (NASA photo)

December 7, 1942 – The first flight of the Bell P-63 Kingcobra, a larger and improved version of the !!!error: Indecipherable SUB-paragraph formatting!!! . While the P-39 was one of the principal US fighters at the start of WWII, its lack of a turbo-supercharger hampered its high altitude performance. Development of the P-63 was meant to address that deficiency, and the Kingcobra was also redesigned with a second supercharger as well as a !!!error: Indecipherable SUB-paragraph formatting!!! wing. The US Army Air Forces showed little interest in the Kingcobra, so the majority of the 3,000 aircraft produced were sent to Russia under the !!!error: Indecipherable SUB-paragraph formatting!!! act, where they fought with great effectiveness, and the Kingcobra proved to be one of Russia’s most successful fighters.

December 8, 2016 – The death of John Glenn. Born on July 18, 1921 in Cambridge, Ohio, Glenn enlisted in the US Army Air Corps following the attack on Pearl Harbor. Seeing no combat action, Glenn transferred to the US Navy, where he flew the !!!error: Indecipherable SUB-paragraph formatting!!! on 59 combat missions over the Pacific. During the Korean War, Glenn flew 149 combat missions in the !!!error: Indecipherable SUB-paragraph formatting!!! , and became a test pilot after the war, where he completed the first transcontinental supersonic flight in a !!!error: Indecipherable SUB-paragraph formatting!!! . Glenn was selected as one of the original !!!error: Indecipherable SUB-paragraph formatting!!! astronauts in 1959, and became the first American to orbit the Earth on February 20, 1962 in !!!error: Indecipherable SUB-paragraph formatting!!! . He resigned from NASA in 1964 to pursue a career in politics, and served as a US Senator from Ohio from 1974-1999. At the age of 77, Glenn returned to space on October 29, 1998 as a !!!error: Indecipherable SUB-paragraph formatting!!! onboard !!!error: Indecipherable SUB-paragraph formatting!!! during !!!error: Indecipherable SUB-paragraph formatting!!! , making Glenn the oldest person ever to fly in space.

The

has become one of the most ubiquitous general aviation helicopters in the world, but it began as a failed bid to provide the US Army with a light observation helicopter (LOH). After losing out to the
!!!error: Indecipherable SUB-paragraph formatting!!!
for the LOH contract, and with an eye toward civilian sales, Bell redesigned what was arguably an unattractive aircraft, while also enlarging the cabin to carry more passengers in greater comfort. The newly designed, and much more aesthetically pleasing,

December 8, 1945 – The first flight of the Bell Model 47,
a single-engine light helicopter and the first helicopter to be certified for civilian operation. The Model 47 was designed by
!!!error: Indecipherable SUB-paragraph formatting!!!
and based on the
!!!error: Indecipherable SUB-paragraph formatting!!!
. One of the key innovations of the Model 47 was the use of a weighted stabilizer bar under the main rotor that helped improve rotor stability during flight. The Model 47 is instantly recognizable by its bubble-shaped canopy with room for two and open tube construction, but later models received a larger, enclosed cabin with room for four. The Model 47 entered service with the US Army in 1946 as the
!!!error: Indecipherable SUB-paragraph formatting!!!
, and saw extensive action in the Korean War, notably as a medevac helicopter. More than 5,600 have been built, a number which includes aircraft built under license in Japan, Italy and England.

I always really liked the P39. Too bad it never really lived up to it’s billing.
Wonder what it would have done with a Merlin, since that was the WW2 aviation equivalent of an LS swap

The majority of the P-63s that did fly for the USAAF were RP-63 “Pinball” target aircraft.
The aircraft was generally painted bright orange to increase its visibility. All armament and the regular armor was removed from these RP-63 aircraft, and over a ton of armored sheet metal was applied to the aircraft. This was fitted with sensors that would detect hits, and these hits were signaled by illuminating a light in the propeller hub where the cannon would have been. This earned the aircraft the unofficial nickname of Pinball . Special frangible rounds made of a lead / Bakelite combination were developed that would disintegrate upon impact.
In August 1944 , Bell modifed five P-63A airframes, removing all armament, replacing much of the forward alumiinum panels with thicker, armoured panels and installing armored glass in the wind screen and side windows. In addition, over 100 microphones were installed behind the armored panels and rigged to indicate hits on a counter in the cockpit. A red light replaced the muzzle of the 37mm cannon in the propeller spinner and was to flash each time the plane was hit by a frangible bullet.
The frangible rounds were capable of taking down a plane if the range was short enough though, or if one made it into the wing root-mounted intakes.
I’d argue the Bell 47 is probably the most widely recognized helicopter, simply from being on M*A*S*H.

Lots
of good stuff here. Hard to choose a favorite entry, but that Bombardier 415 is gnarly.
