Charles Plumb, a U.S. Naval Academy graduate, was a jet fighter pilot in Vietnam. After 75 combat missions, his plane was     by a surface-to-air missile. Plumb was     and spent six years in prison in Vietnam. He survived and now      about lessons learned from that experience.
  One day, Plumb and his wife were sitting in a restaurant when a man at another table came up and said, "You're Plumb! You    jet fighters in Vietnam from the aircraft carrier (航空母舰) Kitty Hawk . You were      !"
"How in the world did you know that?" asked Plumb.
  "I      your parachute," the man replied. Plumb gasped(倒吸一口气) in surprise and     .The man pumped his hand and said, "I guess it worked!"
Plumb assured him, "It     did—if your chute hadn't worked, I wouldn't be here today."
Plumb couldn't sleep that night,thinking about that man. He says, "I wondered how many times I might have passed him      the Kitty Hawk. I wondered how many times I might have seen him and not even said 'Good morning, how are you', or anything     , you see, I was a fighter pilot and he was just a      ."
Plumb thought of the many days the sailor had spent on a long wooden table in the bowels(深处)of the ship      working on each chute, holding in his hands each time the      of someone he didn't know.
  Plumb asks his      , "Who's packing your     ? Everyone has someone who provides what they need to make it      the day." Plumb also says that he needed many kinds of parachutes when his plane was shot down—he needed his      parachute, his mental parachute, his emotional parachute, and his spiritual parachute. He called on all these      before reaching safety. His experience reminds us all to     and be kind to people who pack our daily parachutes, and strengthen us to go through      times.
