Power to weight ratio comment
I remember chatting to a USAF chap (mid 70s?) shortly after the F16 started flying and he was boasting that it was the first jet where the thrust exceeded the weight of the aircraft. I pointed out the Harrier and he said, "Sure that's a good aircraft as well". I highlighted that as it could take off vertically, the thrust must exceed the weight of the aircraft. He paused for a second and then walked off. Didn't see him again!!
