Both engines of the British Airways jet that crash-landed at Heathrow Airport were still running when it came down, investigators have said.
But the engines did not respond sufficiently to a thrust request as it came into land, the Air Accident Investigation Branch (AAIB) said.
US investigators have noted six previous engine failures in the same type of aircraft, it also emerged.

Interesting.
Googles definition for those who don't know the meaning of Thrust in Aviation terms read this:
The force produced by the engines, thrust works opposite of and counteracts drag. Thrust is the forward movement that is necessary to sustain flight. It is one of the four basic principles of flight.
Thrust is the force upon a system (such as a rocket or jet engine) generated when that system expels or accelerates mass. The resultant thrust force is equal to and in the opposite direction of the expelled mass.
So, when you hear the engines getting louded upon landing it means they are getting faster?
Why are the US investigating? Its a British owned, British run jet.
So how does the system work, why didnt it respond to a thrust? What process as such does it go through?
Discuss.
