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.

Two pigeons sneaked aboard a Delta Air Lines plane, delaying the flight twice. The airline confirmed that the pigeons got aboard a flight Saturday that was leaving Minneapolis for Madison, Wisconsin.

On the other hand, pigeons might actually be getting smarter, since a pair in Minneapolis decided to fly to Madison, but instead of taking flight, they took a flight, and now Delta Airlines is a pigeon carrier.
