Lufthansa Flight 2904

Lufthansa Flight 2904 was an Airbus A320-200 flying from Frankfurt, Germany to Warsaw, Poland that overran the runway at Okęcie International Airport on 14 September 1993.Lufthansa Flight 2904 was cleared to land at Okęcie International Airport Runway 11 and was informed of the existence of wind shear on the approach. To compensate for the crosswind, the pilots attempted to touch down with the aircraft banked slightly to the right and with a speed about 20 knots faster than usual. According to the manual, this was the correct procedure for the reported weather conditions, but the weather report was not up to date. At the moment of touchdown, the assumed crosswind turned out to be a tailwind of approximately 20 knots . With the resulting increased speed, the airplane hit the ground at approximately 170 knots and far beyond the normal touchdown point; its right gear touched down 770 metres from the runway threshold. The left gear touched down nine seconds later, 1,525 metres from the threshold. Only when the left gear touched the runway did the ground spoilers and engine thrust reversers start to deploy, these systems depending on oleo strut compression. The wheel brakes, triggered by wheel rotation being equal to or greater than 72 knots , began to operate about four seconds later.
