Interesting theory-I've sat in a few FJ cockpits but never had a trip. For me its like being a kid in a sweet shop but of course flying in FJ's is a very noisy and hazardous occupation for you professionals out there.
Always thought if I ever got a fast jet trip and did get the command to go then I'd be pulling the handle pretty sharpish (self preservation) given that someone in the front seat would be in a much better position to decide on what I should be doing than I would be!
