There is a funny story I have heard about the OV-10, which unfortunately, I cannot verify. As I recall, some Air Force big wig was giving an OV-10 pilot some grief about driving a propellor aircraft and how it would be dead meat if someone had a Stinger. The OV-10 jockey told the guy to grab a Stinger and if he could get a lock, to go ahead and shoot him down. They set the missile up on a hill and waited. The OV-10 pilot came in, inverted, low enough that the big wig was sucking dirt to get below him and by the time he got back up, the OV-10 was gone.
