Passengers on a Delta Air Lines flight from Minneapolis to Madison were surprised on Saturday when two pigeons made an uninvited appearance on board.

A Delta Air Lines flight was delayed twice on Saturday after two pigeons caused chaos onboard. The first bird began flying around the cabin shortly after boarding, prompting the aircraft to return to the gate. Ground crew removed it, but as the plane taxied out for takeoff, a second pigeon took flight, forcing the flight back once again.
