The following footage shows Special Missions Aviation Airmen during preflight, and live fire training mission aboard a U.S. Air Force Special Operations Command AC-130U gunship over Hurlburt Field and the Eglin Air Force Base range.
Noteworthy, the video shows also the ammo upload on the side mounted 40mm and 105mm guns.
It’s quite impressive how’s the huge plane’s cabin seems to be shacken each time a 105mm projectile is fired towards a ground target.
