and just to clear up the 37 sec oops....its the headset lead, it isnt the ground power.........the GPU/FEGP is much thicker than that,god spot tho...still a potential knackered headset
have seen some airports where the tug driver do the headset via a cable as well, using the tug in the clip... very long/stretchy cable.. the guy outside (wingman) closes the headset door and bypass pin removal... i cud be wrong, but i thought there would have been more of a reaction from the guy on the ground if it wasnt meant to be that way
nice idea, but i cant see it catching on
