"I tried to make clear that we never really knew. I dare say those people who were on the ground or anywhere near it and subsequently followed it up would have found out whether it was successful or not. We even tried different sorts of fusing on the bombs to see whether we could, for instance we tried a proximity fuse exercise which meant that the fuse itself looks at whatever it's aimed at and says hey I'm at 300 feet bang and that was designed to destroy foliage over ... overgrowth and also to destroy anything underneath it. So the bombs were set off at different proximities to the jungle coverage and as I say we found out we cleaned up a lot of very good trees and trees look different when they've got no leaves on them but whether we achieved anything for the Army and their purpose in what they were trying to do I don't remember ever hearing."
