Easyjet plane stopped just in time after spanner spotted stuck on wing

An Easyjet flight averted possible disaster after a passenger spotted a spanner stuck on the wing of the plane just moments before take-off. 

According to reports the passenger - known only as Christopher - alerted the pilot who was about to departed on a flight from Geneva to Copenhagen. 

Luckily for all on board the flight was halted just in the nick of time.

"I realised straight away that what I was seeing was not normal," the 25-year-old said, Yahoo News reported. 

"The captain returned to the plane's departure point and a spanner was discovered," an Easyjet spokesperson said. 

"We have opened an inquiry and the authorities have been informed."

An aviation expert told Switzerland's 20 Minutes online news website that if the spanner had fallen on the runway, it could have caused a serious incident - especially if it had been hit by another aircraft.

"It could have caused serious structural damage, just like with the Concorde crash in Paris," he said. 

"If it had stayed attached to the plane, the pilot would have realised when he retracted the flaps about 400 metres from the ground, and been forced to make an emergency landing.'
