Interesting. traveling in the Lear at almost the speed of sound, you really don't notice the speed, especially with plenty of Crown Royal....
Flights are always quick but airports are slow unless you land at a private field, thats not bad. problem is, most private fields don't have enough runway to get airborne on or land on.
Lears do have a 'chute in the tail but it's a one time use and costs 10 grand.
I guess what I'm driving at is I wonder how going from supersonic to transonic impacts the bullet in it's flight path. There has to be turbulence just like in the Lear.
Pretty obvious to me that the guys shooting in the OP's post were just out for a good time.
