IMPERIAL, Pa. -- A beekeeper says he had to be called into gather up a swarm of thousands of bees that delayed a Delta Air Lines flight from Pittsburgh International Airport to New York.
Repasky says such swarms form when colonies become too large and the queen leaves half of her bees behind to find a new home. Some swarms can contain 25,000 to 30,000 bees.
Repasky says it's likely there's a wild honeybee colony at the airport somewhere.
The beekeeper was called to remove the insects because they're a protected species that cannot legally be killed.
