　　Moving the pilot(飞机驾驶员)on the side, the man 10 his seat and 11 carefully to the demanding 12 that were sent by 13 from the airport below. The plane was now 14 close to the ground, but before the passengers got their 15 it soon began to 16 .The man had to circle the airport several times to become 17 with the controls. But the danger had not yet passed． The plane was 18 towards the airfield． It shook violently as it touched the ground, but 19 .Outside a crowd of people rushed forward to congratulate the “pilot” 20 a perfect landing.
