Douglas AC-47D Spooky aka "Puff, the Magic Dragon"

The AC-47 was a United States Air Force C-47 Skytrain (the military version of the DC-3) that had been modified by mounting three .30 in (7.62 mm) General Electric miniguns to fire through two rear window openings and the side cargo door, all on the left (pilot's) side of the aircraft. Other armament configurations could also be found on similar C-47 based aircraft around the world. The guns were actuated by a control on the pilot's yoke, where he could control the guns either individually or together, though gunners were also among the crew to assist with gun failures and similar issues. Its primary function was close air support for ground troops. It could orbit the target for hours providing suppressing fire. Coverage given by a Spooky was over an elliptical area approximately 52 yd (47.5 m) in diameter, placing a round every 2.4 yd (2.2 m) during a 3-second burst.

The plane carried 24,000 rounds of minigun ammunition and flares, which it could drop to light up the battleground.
