What a beautiful sight!
I had the opportunity to control an A-10 gun run during field artillery school at Fort Sill, OK 40 years ago. I can still remember seeing the devastating effects of the target hits and the inimitable BBUURRRPPPP from its 20mm? or 30mm? guns (long time ago).
I sat left seat in an OH-58 during JAATs (Joint Air Attack Team) in the early ‘80’s. Arty, Cobras, OH-58’s and A10’s in a synchronized dance.
30MM.
Two distinct sounds when shooting: Mini-sonic booms from the bullets and then the sound of the gun firing.
