Delta flight delayed by swarm of bees on wing at Houston airport.

A Delta Air Lines flight from Houston to Atlanta was delayed for three hours after a swarm of bees briefly colonized one of the plane's winglets. The bees were eventually dislodged when the aircraft was pushed back from the gate, allowing passengers to board and resume their trip. Delta said the flight was delayed to ensure the bees' welfare and to make sure no safety-critical surfaces of the plane were contaminated. The airline apologized to the 92 passengers aboard for the delay and said bee swarms like this are unusual but not unheard-of.
