these things happen all the time.
combination of fear, stress, fatique, sleep deprivation, drugs, etc.
any of you guys ever gotten shot at? at a party, outside a club, on the street, etc.?
everyone goes crazy, run around, ducking, diving.....
afterwards, confusion, no one knows what really happened, everyone saw different things, different stories....
thats just some guy lighting off a revolver or pistol a couple rounds....
imagine assault rifles, machine guns, rockets, grenades going off.
aircraft friendly fire is a different animal. usually bad intel.
the control will tell the pilot no friendly forces in the area, hard to tell friend or foe from 10,000 feet, even with optics.... they light them up because SUPPOSEDLY no friendlies in the area.
the friendly grunts start screaming in their radios but by the time the control tell the pilot they usually already hit something.
