Zayn Malik thought the plane would flip upside down when he first went on a flight.
The One Direction heart throb had never flown before his time in the boy band and his bandmates tricked him into thinking the plane would do "a loop the loop".
Speaking on The Jonathan Ross Show, he said: "The first time I went on a plane, I went on a plane with these boys.
"And they knew that it was the first time I was getting on a plane and I was quite nervous about it.
"So before the plane took off I'm sat with Louis on one side and Liam on the other and Louis goes, 'Right, when it takes off it's going to do a loop the loop in the air.'
"So I remember for twenty minutes of the journey I was waiting for it to go upside down. It just terrified me."
The 'Story of My Life' hitmakers - completed by Harry Styles and Niall Horan - also insisted they will be together for "a long time", with no plans to go solo.
Harry insisted: "I think we're just so busy at the moment that there's no way we would have time anyway, but I think we just have so much fun, doing this and we want to all be doing this for a long time.
"So I just think we'll keep working hard and having fun and see what happens."
