The speed of the world's biggest jets was no match against the slow and steady pace of a group of turtles who delayed flights at New York City's John F. Kennedy International Airport on Wednesday morning, Reuters reported. A runway that juts out into a bay was closed for 35 minutes while 78 diamondback terrapin turtles, each weighing 2-3 pounds (1-2 kilograms), were removed, said a spokesman for airport operator The Port Authority of New York and New Jersey. "They came up out of the water," the spokesman said. "It happens, but it doesn't happen a lot." The closure caused delays of 1-1/2 hours at the airport, which caters to about 48 million passengers a year. The turtles were taken away and released back into the wild -- away from the airport.
