The Survivor

The pilot is seen switching off the "No Smoking" and "Fasten Seat Belt" signs almost immediately the plane is airborne, yet just a few seconds later it can be seen that the wheels have not been retracted.

The signs would have been kept lit until the plane was well into the air, which would be some time after the wheels had been retracted.

During the takeoff roll, the first officer calls "Vee-one", then "Vee-two", then "rotate".

V2 is the climb-out speed with an engine failure, and is never less than the rotate speed, so would not be achieved until the aircraft is airborne.
