If the helo was flying low/NOE, it'd be a brave Mustang pilot who made a
diving attack.

It happened many times during WW2 and Korea just not against helicopters.
Have
you never heard of a strafing run? P-51s made a lot of runs against low
flying
aircraft as well as stationary targets.

Well at least one AN-2 has been shot down from a UH-1
