Apparently, nothing can stand in the way of a turtle's libido—not even a 747.

"Running over turtles is not healthy for them," says a Jet Blue rep. "Nor is it good for our tires."
"The sandy spot on the other side of Runway 4L is ideal for egg laying," says an airport spokesman. "It is a naturally provided turtle maternity ward. When your airport is virtually surrounded by water, your neighbors sometimes come in the hard shell variety." A runway at JFK was also closed in July 2009 when 78 turtles crawled from nearby Jamaica Bay. (Read more turtles stories.)
