On 19 December 2023, the flight crew of a Boeing 737-400F making a night takeoff at Amsterdam experienced difficulty in rotating the aircraft to a lift-off attitude but after applying much more backward pressure on the control column than usual, it was possible to get airborne and no more aircraft control problems occurred. After completing their short flight to Brussels without further event, the crew were informed that the load and trim sheet provided and accepted had not shown the correct information because the usual cross checks before presentation to the crew had not been performed.
