Give me some "holy sh... did that just happen" ideas

No doubt this must have been covered before.
How about those hair-raising secondary explosions we see in guncam footage of strafing attacks on rail cars or trucks.
Strafe the wrong rail car and a great load of metal, ammo and debris shoots up several hundred feet right in front of you !
I've seen many guncam clips of this that make it seem impossible that the pilot flew thru all the junk and lived.

That'll put the fear of god in you.
