Reminds me of the 727 (i think) aircraft that crashed on departure from Heathrow back in the 70s.(27L/R runways - it hit ashford or somewhere west of airfield I know that) Dad was one of the first people on the scene!!
The truth emerged about the slats (leading edge), being retracted too soon, thus resulting in increased drag and reduced lift due to decreased accel.
Anyone care to elaborate for me?
