Pissed Off Passengers

Two planes had to circle for 18 minutes because the lone air traffic controller at the airport in Manchester, New Hampshire used the bathroom.
The only other employee in the tower was a trainee and not certified to handle takeoffs and landings.
Passengers on the aircraft were probably not informed of the reason for the delay.
During the controller's break, a pilot on one of the planes radioed the tower and spoke to a trainee, who was not certified to conduct controller operations. The trainee told the pilot he would have to wait 10 minutes for the controller to return.
The pilot replied that he had "lungs on board," preparing to be transplanted.
