According info leaks somebody in the cockpit told : "speed 300.... f*ck, flaps!!! "
That's why there is a version that one of pilots selected flaps from 28 to 0 inadvertently.
That's incorrect data. According Tu154 SOP in case of T/O with flaps 28:
- configuration change 28-15 - at speed 330-340 km/h
- from 15 to clean wing - at not less than 350 km/h
- 380-400 km/h (depending on weight) must be provided at the end of transition
So if they had 300 with clean wing.....
