From the video description: “4th Special Operations Squadron Airmen conduct a live-fire training exercise mission in an AC-130U Gunship during Emerald Warrior 2015 at Hurlburt Field, Florida.”

A howitzer in an airplane. How crazy/cool is that? Which gets me wondering, how do they aim it?

Wikipedia to the rescue, sort of:

Mission systems:

Raytheon AN/APQ-180 multimode attack radar – enhanced version of AN/APG-70 radar (used on F-15E Strike Eagle ) incorporating several enhanced air-to-ground modes such as fixed target track, ground moving target indication and track, projectile impact point position, beacon track, and a weather detection [71] [73] [74]

Raytheon AN/AAQ-26 IDS – LWIR FLIR (mounted on port side of the nose landing gear door) [71] [72]

Lockheed Martin AN/AAQ-39 Gunship Multispectral Sensor System (GMS2) – EO/IR fire control system consists of mid-wave infrared (MWIR) FLIR, two Image-Intensified Television (I2TV) cameras ( CCD-TV ), laser target designator/rangefinder with eyesafe mode (1064 and 1570 nm dual mode laser emitter), and near-infrared (NIR) laser pointer/marker (860 nm laser emitter) (mounted under the nose of port landing gear sponson) [75]

Sort of indeed. With the plane orbiting a fixed point over the ground, I imagine it’s probably a pretty simple solution to come up with barrel angel and all that. But I cannot into math.

They probably have multiple abacuses (abacii?) and sextants.

abacus (n.) late 14c., “sand table for drawing, calculating, etc.,” from Latin abacus , from Greek abax (genitive abakos ) “counting table,” from Hebrew abaq “dust,” from root a-b-q “to fly off.” Originally a drawing board covered with dust or sand that could be written on to do mathematical equations. Specific reference to a counting frame is 17c. or later. ( etymonline )

Since the meaning of abacus as a counting frame only dates back to the 17th century, I would wager that the plural is abacuses .

Only on Oppo can a video of a deadly war machine turn into an analysis of the etymology of the word abacus. :)
