 The September 11 Attack on the Pentagon  
Portable diesel generator, hit by the plane’s right wing

This large portable diesel generator, hit by the plane’s right wing, had provided backup power to Wedge 1 of the Pentagon.

Pentagon employee Frank Probst was walking across the Pentagon grounds as Flight 77 approached, heading directly for him. He threw himself to the ground and the plane passed directly over him. Probst saw the tip of the plane’s right wing strike and cut through the generator, pushing it aside at an angle. The right engine hit the chain link fence, creating the hole in it. After the crash, tiny pieces of plane debris fell around Probst. (U.S. Marine Corps)
