One particular problem the Blue Angels had (at least when I visited them years ago) was that the video recorder they used to tape the passengers, tended to fail during the flights, when the g forces became excessive. The g made the recording head slip off the tape, as was demonstrated on one of my rides. It kept going until 7g and then "zip" - goodbye picture. Dunno whether they ever solved this problem or if they've gone digi or something...
