According to CNN Travel News a Canadian pilot paid a visit to the toilet and found himself locked out of the cabin.
The Jazz airlines plane was on a flight from Ottawa to Winnipeg. With 30 minutes remaining, the pilot was seen frantically banging on the cabin door by passengers. The crew had to remove the door from its hinges to let the unfortunate pilot back onto the flight deck.
A spokeswoman for Jazz said that at no time had the plane or passengers been in any danger.
There must have been a few red faces on the cabin deck though!
