From the recordings, air-traffic controllers can be heard asking for clearance for the private jet to take off on its flight to an airport in Van Nuys, California. Everything seems to be going well at first, then a controller at South Carolina's Columbia Metropolitan Airport can be heard saying, "We've had an emergency -- sir, you're not going to be able to land runway 1-1. We've had an emergency -- fly straight ahead."
