An Alaska Airlines flight had a scary moment when a part of the plane came loose and created a big hole in the fuselage.
Flight attendants were worried that passengers had been pulled out of the plane because they saw empty seats near the hole.
Even though it was a scary experience, the pilots managed to land the plane safely back at the airport.
Experts are now investigating what caused the part of the plane to break off and are talking to people on the flight to find out more.
