A Ryanair flight to southern Germany had to return the Greek city of Thessaloniki on Friday after a passenger window broke shortly after takeoff.

The pressure difference pulled the head and shoulders of the man sitting by the window outside the aircraft, and a desperate rescue effort ensued.

What happened on the Ryanair flight?

Travelers heard a loud bang during Friday's flight to Memmingen Airport in Bavaria after which the window pane smashed, and oxygen masks dropped from the ceiling.

The passenger sitting by the window had kept his seat belt fastened, which helped prevent him from being pulled farther out of the aircraft and eased the rescue, a witness told Radio Thessaloniki.
