A passenger was partially sucked through a dislodged window on a Ryanair flight shortly after take off from Thessaloniki in Greece, two airport sources say, forcing the aircraft to make an emergency landing. The plane was scheduled to fly from Thessaloniki to Memmingen airport in Germany but returned to Thessaloniki "when a passenger window dislodged inflight," Ryanair said in a statement. It is unclear what led to the broken window.
