Falling asleep at the controls, landing in the wrong country and near crashes with other aircraft.
They are some of the mistakes pilots reported on a website designed to help them and flight staff identify common errors and improve the quality of their service.
Each report on the NASArun Aviation Safety Reporting Program - which details more than 300,000 errors - is verified and published anonymously after being submitted by a flight crew, air traffic controllers or maintenance workers.
One report reads: "The bright sun shining in the windshield made the cockpit very warm and me very relaxed. The next thing I remember was being awakened by control calling me on the headset. I had fallen asleep, when I woke up I was descending. That is what control was calling me about."
The reports may appear scary but aviation safety experts said passengers should not worry.
A spokesman for the British Airline Pilots Association said: "Flying is still the safest way to travel and passengers have no need to worry.
"But pilot fatigue is an extremely worrying problem which is being made worse by new regulations from the European Union whereby pilots are flying longer hours with shorter breaks."
