Lufthansa Flight 2904 - Description of The Incident

Description of The Incident

Lufthansa Flight 2904 was cleared to land at Okęcie International Airport Rwy 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. Additionally they landed with a speed about 20 knots (37 km/h) 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 touch down, the assumed crosswind turned out to be a tailwind. Due to the tailwind of approximately 20 knots (37 km/h) and the increased speed the airplane hit the ground at approximately 170 knots (310 km/h) and far beyond the normal touch down point. The aircraft's right gear touched down 770 m from the runway 11 threshold. The left gear touched down 9 seconds later, 1525 m from the threshold. Only when the left gear touched the runway did the ground spoilers and engine thrust reversers deploy, these automatic systems depending on oleo strut (shock absorber) compression. The wheel brakes, triggered by wheel rotation being equal to or greater than 72 knots (133 km/h) began to operate after about 4 seconds. Seeing the approaching end of the runway and the obstacle behind it, the pilot steered the aircraft off the runway to the right. The aircraft departed the runway at a speed of 72 knots (133 km/h) and rolled 90 m before it hit the embankment and an LLZ aerial with the left wing. A fire started in the left wing area and penetrated into the passenger cabin. Two of 70 occupants died in this accident, including the co-pilot who died on impact and one passenger who was unable to escape because he lost consciousness as a result of the smoke in the cabin.

Marcin Bronikowski, a passenger, told Warsaw Radio ZET station that the incident occurred "in a fraction of a second after landing" and that "there was even hand-clapping after the landing."

    God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.
    Lyndon Baines Johnson (1908–1973)

    I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.
    Henry David Thoreau (1817–1862)

    I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.
    Thomas Jefferson (1743–1826)

    “It is of the highest importance in the art of detection to be able to recognise out of a number of facts which are incidental and which are vital.... I would call your attention to the curious incident of the dog in the night-time.”
    “The dog did nothing in the night-time.”
    “That was the curious incident.”
    Sir Arthur Conan Doyle (1859–1930)
