Flights crawled to a stop at one of the world's busiest airports this morning when it was invaded by turtles! One runway was closed at New York's JFK Airport when about 150 Diamondback Terrapin turtles were spotted crossing the tarmac. The mama turtles were trying to get to the other side to lay eggs on the shores of the Jamaica Bay Wildlife Refuge, which borders the airport. Ron Marsico, a spokesman for the Port Authority of New York said pilots from Jet Blue and other airlines halted their flights to let the expectant turtles pass. But he brushed off the turtle invasion saying: "Flight delays attributed to turtles were minor, about 15 minutes or so." People began tweeting about the turtles soon after the news broke. Within 8 hours, @JFKTurtles had almost 3,000 followers on Twitter. It's nice hearing these stories. Think of the alternative had the pilots been jerks.
