Nothing can fly low and slow and linger over the target like the Warthog. Best ground support plane ever.
The A-10 is the “People’s” plane. Hardworking, no frills, effective.
For its time, AD Skyraider was a better plane - lower and slower. Flew from 1946 until they literally flew the wings off in Vietnam. The single engine AD was designed originally as a torpedo bomber to replace the Helldiver and Avenger. It could carry more bombs than a B-17.
Marines with squadrons in Korea reported that some crashed on landing because of mud on the windshield or telephone wires entangled in the flight controls. Now, THAT is low and slow.
All in all, the Warthog fills some mighty big shoes. Would dearly love to see what my Marines could do with it.
