1994 Fairchild Air Force Base B-52 crash
On Friday, 24 June 1994, a United States Air Force (USAF) Boeing B-52 Stratofortress crashed at Fairchild Air Force Base, Washington, United States, after its pilot, Lieutenant Colonel Arthur "Bud" Holland, maneuvered the bomber beyond its operational limits and lost control. The aircraft stalled, fell to the ground and exploded, killing Holland and the other three crew aboard. The crash was captured on video and was shown repeatedly on news broadcasts throughout the world.

In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number.
