I have a hard time imagining how two airplanes could collide in mid air like this.
PILOT-1: "We're gonna turn left, right?:"
PILOT-2: "Yeah, right."
Luke AFB, AZ 1998 two F-16’s collide. One jet crashes, pilot killed. The other damaged jet managed to return to base.
Shaw AFB, SC 2007? two F-16’s collide over the Atlantic coast. One pilot is able to IFE into Myrte Beach. The other crashes into the ocean. DNA on the jet that landed determine the pilots canopy impacted the missile rail of the other jet.
It happens.
Flying and fighting is an extremely dangerous duty. To fight effectively military pilots must do things most people would consider crazy and they must train the same way they will fight. Thank God for all those who are "crazy" enough to fly and fight and for such great professionalism that these accidents are rare occurrences.
The 3D space and hard-to-judge rates of closure make collision very likely without skill at flying in close proximity to other airplanes.
I enjoy watching birds fly in pairs, they do some amazing things to avoid ramming each other.
