Thomas Cook flight TCX1638 had to return and make an emergency landing at Gatwick airport in West Sussex, UK, on October 31.
The Boeing 757-3CQ departed from the airport at around 9 a.m. and was heading to Hurghada, Egypt, when its emergency slide unit fell off. The pilot was then instructed to turn back and land at Gatwick.
The flight landed safely and all 237 passengers remained unharmed. The passengers were shifted to another flight.
It is believed that the emergency slide fell near the border of Kent and East Sussex. The local police were informed and they sent search teams to spot the unit.
Thomas Cook and the Air Accidents Investigation Branch are investigating.
