On 1 December 2021, a lightly loaded Boeing 737-800 became airborne near the end of the runway at Kuusamo with only engine run-up thrust set with only the abnormally low climb rate alerting the crew to their error. Serial failure by both pilots to follow relevant normal takeoff procedures followed after the type-experienced First Officer had been surprised when the aircraft began to move because his inexperience in brake use resulted in insufficient brake pressure being applied during the engine run-up. The Captain’s failure to notice the error was associated with allowing himself to be distracted by a non-urgent radio call.
