A pack of sex-starved turtles shut down a Kennedy Airport runway Wednesday by crossing the tarmac to get to their seasonal breeding grounds.
"JFK is experiencing delays as the airport clears turtles off the runway," JetBlue Airways wrote on its Twitter feed around 9:40 a.m., adding the hashtag "cantmakethisup."
Airport workers helped clear runway 4L of the slow-moving diamondback terrapins who were headed to their natural breeding grounds in Jamaica Bay.
JetBlue justified the delay by noting, "Running over turtles is not healthy for them, nor is it good for our tires."
Federal Aviation Administration Arlene Salac said it is required to shut a runway if "there is any kind of object or debris on it."
"Crews were called in to help speed things along," she said. "It didn't have a significant impact on operations."
It's not the first time the mating ritual has held up traffic at the airport.
In July 2009, some flights were delayed for up to 90 minutes as crews cleared a runway of 78 turtles.
The reptilian renegades are not the only wildlife to cause headaches at the city's airports.
Flocks of geese have damaged incoming and outgoing planes - most notoriously causing the "Miracle on the Hudson" crash of US Airways Flight 1549 in January 2009.
The episode led to campaigns to cull geese living around JFK and LaGuardia.
