Mrs．Smith’s husband went off on a business trip to Australia．He wanted to catch the 3∶30 plane to Darwin．She was very surprised when he telephoned her at 5 o’clock and said that he was still at the airport．
“What happened?” asked Mrs．Smith．
“Well,” said Mr．Smith, “everything was going fine．I got my ticket, checked my luggage and waited in line at the gate．I walked across the runway to the airplane and I saw my friend Jack Scott．Jack was an airplane engineer．I shouted to him and a policeman caught me．”
“Why did he catch you?”
“I don’t know,” said Mr．Smith．“All I said was ‘Hi, Jack’!”
The word “hijack” means “to take control of a plane by force(劫機)”．
