Seem to remember that somebody nicked a 707 at one of the Bristol Airports back in the 1980s, allegedly knocking half the approach lights down as it rotated and slowly climbed .. also apparently with only a PPL in the Right hand seat. I remember the newspaper headline about the "Bristol Cowboy".
But as a simple cherokee driver ..... how do you start a 727 that has sat on the ground for 14 months ??? Won't the battery be flat ??? ... I asume you'd need that as a minimum to get the APU going or else one man on his own would take all night setting up a houchin cart, starting the apu, getting out, shifting the cart etc.
Personally I wouldn't even know how to get the back stairs on a 727 down without power and assume that first you'd have to nick a tractor and a set of steps just to get in the door ???
I hear what is said about "Welcome to Africa" ... but wouldn't all that runnin' about and racket attract some attention ???
