Ah, an HF aerial. 30' thats OK then. Wasn't Smoky was on the Unit Inquiry?
Taxydual: you are quite correct, Smokey was in charge of the inquiry. Seem to remember the F4 pilot was known as "Kenny", shared the same surname as a well known comedian at the time.
I also believe that he took the aerial wire whilst at a high angle of bank so wingtip clearance was not a lot.
Locals did indeed deny it but word soon got around that they thought it was the best flyby seen.
