JetBlue says one of its planes aborted a takeoff at Kennedy International Airport when another aircraft suddenly crossed the runway.

JetBlue spokesman Rick Clark says Flight 1295 to Austin, Texas, was cleared for takeoff on Saturday evening and rolling down the tarmac at full speed when the pilot was forced to put on the brakes.

Clark says there were no injuries.

The JetBlue plane returned to the gate and took off for Austin three hours late.

Clark says he doesn’t know exactly how close the two planes were.

JetBlue officials say Caribbean Airways Flight 526 crossed the runway without authorization. No one was immediately available for comment at Caribbean Airways.

The Federal Aviation Authority did not immediately respond to a call seeking comment.
