Crab,
Sometimes you do come across as a bit of a prat
Watch the video again: the groundcrew, see those funny things they all have on their heads? Headsets, with radio comms.
See the crewman in the doorway, watching the procedure? Bet he's not there for fun.
Out of sight, for'd of the pilot? LSE, giving guidance to the pilot.
Out of sight, behind the camera? Flyco, with the Air Boss (we used to have Little F and Wings, but I hope I have the USN term right) in radio comms with the airframe drivers
and the groundcrew.
Last guy out when the wheel is unlocked? He seems pretty much in charge around the machine, bet he's the maintenance crew chief, and is following SOP's for this event. And guess what? He's on comms with a headset
You've had a lot of advice on this thread, none of which seems to have sunk in.
Except SASless' bait, which seems to have been swallowed whole
