Chris Weston -
Funny that you mention that I should read the AAIB report. I have, and reread it to see if anything new had been released. No new news.
Here's the facts as released by the AAIB. This is the only description of the flight crew's actions during the event.
Absent a release of factual data the rest is speculation.
control for the landing at a height of approximately 780 ft,
in accordance with the briefed procedure, and shortly
afterwards the autothrottles commanded an increase in
thrust from both engines. The engines initially responded
but, at a height of about 720 ft, the thrust of the right engine
reduced. Some seven seconds later, the thrust reduced on
the left engine to a similar level. The engines did not shut
down and both engines continued to produce thrust at an
engine speed above flight idle, but less than the commanded
thrust. The engines failed to respond to further demands
for increased thrust from the autothrottles, and subsequent
movement of the thrust levers fully forward by the flight
crew. The airspeed reduced as the autopilot attempted to
maintain the ILS glide slope and by 200 ft the airspeed
had reduced to about 108 kt. The autopilot disconnected
at approximately 175 ft, the aircraft descended rapidly
and its landing gear made contact with the ground some
1,000 ft short of the paved runway surface just inside the
airfield boundary fence.
Lots of questions, few answers. I'll await the official report before calling anyone's actions 'heroic'.
