Hello,
Here's one that we missed, Clint Eastwood. He learned to fly helicopters at Palomar/McClelland field in Carlsbad, Ca in the early 90's. In fact, he walked by me twice and I didn't recognize him until later in the day he bought a sectional in the pilot shop on the field. Didn't talk to him, but watched him doing autorotations in Hughes 300.
As for John Travolta, he recieved training at through a publicity deal with QANTAS, but is not type rated in the 747-400. Nor is he typed in his own 707-138B. He employs a full-time crew to fly the airplane, and "acts" as PIC. I don't think he'd get insured until he gets a little more time. He is typed in the Lear, Gulfstream and strangely enough VFR only in the Citation.
I'm not certain, but I think that Greg Norman (Aussie golfer) is a pilot too. He owns more than a couple of aircraft and helicopters. He is a very savvy business man like Arnold Palmer and is a millionaire many times over independent of his golf career.
One last celeb thats a pilot, albeit from years ago. Bob Barker is a former Naval Aviator. Trained at the end of the war, he didn't reach the Pacific theatre until the end of hostilities and was honorably discharged.
Not sure where Worf picked up the "5,4,3,2,1" thing, but he's had a flight with the Thunderbirds, so I might have picked it up from them. Otherwise as far as military tactical jet operations are concerned. Most (if not all) inter-flight communications while flying formation is accomplished through hand-signals. This is done for a couple of reasons. First, if you go "NORDO" (No radio) and operating with hand signals makes the transition to NORDO much more seemless. Second, if in EMCON (Emissions Control) "chit-chat" on the radio is about THE easist way short of turning on your RADAR of telegraphing where you are to the enemy. Given the current state-of-the-art data link systems that are not only highly directional (making them extremely difficult to jam or spoof) talking on the radio anymore than absolutely necessary unprofessional and possibly fatal. One exception to that is helicopters. Just a little triva for y'all out there.
