That Saudia 743 with its nose in the drain was not during take-off or landing. It was being taxied out of a engine run pen and IIRC they did not have hydraulics fully on line, hence no steering or brakes.
Yep, maintenance guy taxied it out of the gate with unqualified helper in FE seat.
Declined help of tech crew sitting in the upper deck.
Taxied at warp speed - without Hyd for brakes/steering.
Sad end to a great aircraft just out of overhaul AIO
