A moment of celebration turned into a big hassle for passengers aboard an easyJet flying from London to Dalaman, Turkey.

The Aug. 7 incident occurred on flight EZY8845, according to The Telegraph. A flight attendant was opening a bottle of champagne for a passenger when the cork flew out and damaged ceiling panels in the plane.

The damage caused oxygen masks to drop.

The captain of the plane decided to divert the plane to Italy because the air crew’s oxygen masks needed to be reset, according to an official statement from easyJet.

After a delay of several hours, the flight resumed without further incident.

CNET reports that a bottle of champagne contains 90 pounds per square inch of pressure, and scientists believe a cork pops at a speed of roughly 25 mph.
