As Air Force One journeyed from the US to the UK this week, it came within eight lateral miles of a Spirit Airlines flight heading up the East Coast from Fort Lauderdale to Boston. An alert air traffic controller in the New York control center reached out to the Spirit flight, telling it to execute an immediate right turn to avoid any possibility of colliding with Air Force One.
But the Spirit pilots did not respond immediately, leading the testy air traffic controller to scold them repeatedly. (You can listen to the audio archive on LiveATC.net; it begins at around the 23:15 mark.)
"Pay attention!" said the controller after his first instruction was not acknowledged. "Spirit 1300, turn 20 degrees right."
No reply.
"Spirit 1300, turn 20 degrees right now," the controller added a few seconds later.
No reply.
"Spirit wings 1300, turn 20 degrees right IMMEDIATELY!"
This time, the controller received an acknowledgement, but he made sure to let the pilots know that he was displeased with their response times, giving them another "Pay attention!"
The controller then provided the background for his request.
"Spirit 1300, traffic's off your left wing by 6, uh, 8 miles. 747. I'm sure you can see who it is... Keep an eye out for him. He's white and blue."
