The pictures are totally genuine. I can see jet efflux, the take-off flaps are set, the whole sequence looks genuine- what more do you people want? If the wind is indeed as stated, he may well have lifted off further back than people realise, but the angle of climb is less- ie he still only climbed at a reduced rate, but with a greater groundspeed due to the tailwind it resulted in a low angle of climb. Looks worse than it is, especially as a long telephoto was used, but still disturbing.
