TU-154
In the mid-90's I flew Balkan Airlines (Tu-154) from Harare (Zimbabwe) to the UK stopping 4 times. Plane completely full of pax, high altitude runway, though fortunately very long. Plane rotated but did not take off. Nose was lowered, engine noise increased noticeably and we continued for several seconds more before second rotation and liftoff, right at the end of the runway. Most anxious moment I have ever had as a passenger. I wonder now if flaps/slats were incorrectly set, but I am not sure of this type. Anyone know more about this Tupolev type and configuration?
