The giant planes in the airport on VCS you can actully get in, although you cannot drive them
so you have to wait for it to complete its lap, takes about 5 mins
to do this grab anm ambulance drive to the air port, position the ambulance and get on, jump on the wing of the plane as it come round, and run inwards to the plane pressing triangle, to exit wait for the plain to come to land on the runway, when it starts to descend tap triangle over and over until you jump out
;) have fun
