I am used to travelling by air.Last Wednesday,I flew to Europe from China.The plane took off on time.A passenger who has never been by air before threw a lighted cigarette into an air vent.Because he thought it was an ash tray.Almost immediately smoke rose up and covered the plane.A flight attendant told us that somewhere fired on.Everybody on board was panicked and we were curious to find out how the fire was put out,when the plane suddenly turned round and returned to the airport.In the meantime,fire engines and ambulances hurried to come here in time.After the plane had landed,we all went out of it.Fortunately,no one was hurt.After some times,the fire was put out and the plane took off again.
