Excellent post Kalistan but it does not mean an excellent question .....
Try yourself in a sim and you would be surprised to see the result even with LG down + full speedbrake .........
Bear in mind that the aircraft involved was a non 'E' model, therefore, speedbrake is only avail up to Conf 2 or less .......
Until then, I think the crew did an excellent job to put the tube on the tarmac in one piece with 0 loss of life .........
