Not a chopper pilot - but have often mused on the link between choppers and bikes.
As a lad, often thought the Hughes 500 (favourite machine) looked like it would feel like a high performance motorbike to fly - fast, maneuverable and demanding.
Sort of like my Ducati MS2R800 Monster with Sparks pipes.
Red, loud (they might not see you, but they can sure hear you...) and if not treated with the utmost respect... lethal.
