Flight 712, scheduled to depart from Heathrow's Terminal 3 at 16:15
BST (15:15
GMT), took off from Runway 28L at 16:27
BST (15:27
GMT). It had 127 people aboard, including a crew augmented by the addition of an acting
flight officer, John Hutchinson, and a check captain for routine
performance review of the pilot in command, Captain Cliff Taylor. As well as the passengers, the aircraft was carrying baggage, mail and a
radioactive isotope from the Isotope Production Unit at
Harwell destined for the
University Hospital in
Jerusalem. Seconds after takeoff from Heathrow's then-
runway 28L (extended, years later, and now re-designated as 27L), there was an unexpected bang and the aircraft started vibrating. The
throttle controlling number two engine was shutting down. While Taylor ordered an engine failure drill,
Flight Engineer Thomas Hicks carried out the engine failure drill, but both he and Check Captain Geoffrey Moss reached for the switch to cancel the
undercarriage warning horn. At the same time,
First Officer Francis Kirkland inadvertently cancelled the fire bell. Hicks reached for, but did not pull, the engine fire shut-off handle. Cabin crew member Jennifer Suares repeated the emergency landing drill for passengers. He also instructed two other aircraft to perform a
go-around, as runway 05R crossed runway 28R, which they were due to land on and Davis did not know whether Flight 712 would be able to stop before reaching that runway. The crew accepted Davis's offer of runway 05R, even though it was much shorter and not equipped with
ILS. The aircraft
touched down about beyond the threshold and stopped in . ==Passengers==
