On August 6, two pilots and five passengers aboard a Wheels Up Citation Excel XLS were in for a scare when the door swung open as the plane climbed to 2,000 feet.

"The door is hanging and uh… passengers… I think they're okay but they're gonna be pretty upset," the pilot said in recorded correspondence with an air traffic controller.

The chartered business jet had just taken off from the San Francisco International Airport and was en route to Drummond Island Airport in Michigan, when its pilot declared an emergency and asked to return to the airport.

Om maar even met de 'open deur' in huis te vallen, vrij amateuristische RT van beide partijen.
