G-ARWE
Just as an aside re "1968 BOAC Boeing 707 G-ARWE was destroyed in a fire at Heathrow."
A few years ago I met one of the cabin crew who was onboard the above aircraft, and has survived to this date. One gallant crew member stayed as long as she could, but sadly perished.
G-ARWE on which plenty as been written, was brought back to Heathrow, already with an engine fire, and then the resultant fire destroyed the aircraft. The engine that left the aircraft was discovered in a flooded gravel pit, now Thorpe Park.
