Watch: Loose pigeons cause havoc on plane before take-off
A Delta flight travelling from Minneapolis to Madison, Wisconsin was delayed after two pigeons ended up onboard the aircraft, baffling both passengers and crew.
Video shows one of birds flying through the cabin as a passenger attempts to catch it with a jacket. According to local media, baggage handlers were called on board and safely removed one of the birds.
However, as the plane began to taxi down the runway, a second bird emerged, causing the pilot to contact air traffic control to return to the gate once more.
The flight arrived in Madison one hour later than scheduled. Delta later apologised to customers for the delay.
