I believe the [abbreviated] sequence of events might be:
"Switches on."
"Right, start No.1"
"Start No.2"
"SUNRAY, REQUESTING PERMISSION TO TAXI"
"PERMISSION GRANTED, SUNRAY, TAXI TO THE THRESHOLD OF RUNWAY NINER"
... a series of unintelligible noises...
"SUNRAY, REQUESTING PERMISSION TO TAKE OFF"
ROGER SUNRAY, PERMISSION TO TAKEOFF"
"SUNRAY, ... ER ... WHEELS UP AT 49 PAST THE HOUR"
Hmmm... very interesting indeed...
