Iām serious. I believe it was Bob Bishop who spent several weeks flying cruise missile profiles against the DC area out of Ocean City MD in a BD-5J. The CAP did light GA profiles in 172ās. It was all about having enough time to make a good friend/foe decision and warn off non-bandits before it got so close they had to splash the bogey.
Actually it proves they work ā they were able to keep all 8 from getting so close before they were identified that they had to be splashed.
