Turbo Rick : 10 points !
although meant as an example ( an unlikely event especially seen the dep time . ) but valid remark !
Something else : seen on TV a visu of the radar track ( the Sharm radar was apparently diverted to Cairo and recorded ) climb to 4800 ft without problem then abrupt near 180 degr turn and a dive descent , end of recording and presumably crash 17 seconds later. But impossible to verify if this is the correct version or a journalist made up scenario. so caution.
