After a long flight in the hot sun, it may be nice to cool off and rest at the local flight center—and that’s what about 10,000 bees did at a Massachusetts airport recently.

The swarm of honeybees landed on the wing of a flight school’s Piper Warrior at Beverly Municipal Airport and later found a shady spot on its underside. A local bee expert removed the bees with a special vacuum and transported them to where they could produce honey.

“I’d never seen anything like it,” said Arne Nordeide, the owner of Beverly Flight Center. He said that beekeeper Al Wilkins told him that in the sunny and windy conditions that day, the bees “just got tired and decided to take a little break.”
