I put my carry-on in the luggage compartment(行李舱架),

and sat down in my seat.Just before take-off,a line of soldiers came down the aisle（过道） and filled all the empty seats.

After flying for about an hour,an announcement was made that sack lunch （午餐袋）were available for $5.As I reached for my wallet to buy one,I overheard the soldier ask his buddy if he planned to buy lunch."No ,that seems like a lot of money for just a sack lunch.I'll wait till we get to Chicago."His friend agreed.

I looked around at the other soldiers.None were buying lunch.I walked to the back of the plane,and handed the flight attendant（服务人员）a $50 bill." Take a lunch to all those soldiers."

After we finished eating. I went again to the back of the plane,heading for the restroom.A man stopped me."I saw what you did.I want to be part of it.Here,take this."He handed me $25.

Soon after I returned to my seat,I saw the Flight Captain coming down the aisle.

When he got to my row,he stopped and said,"I want to shake your hand.I was a soldier and I was a military（军队） pilot.Once,someone bought me a lunch.It was an act of kindness I never forgot."I was embarrassed when applause（掌声） was heard from all of the passengers.

Later I walked to the front of the plane so I could stretch my legs.A man who was seated about six rows in front of me reached out his hand,wanting to shake mine.He left another $25 in my hand.

We landed in Chicago,I picked up my belongings.Waiting just inside the airplane door was a man who stopped me and put something in my shirt pocket.Another $25.

Upon entering the terminal（航站楼）,I saw the soldiers gathering for their trip to their base.

I walked over to them and handed them $75."It will take you some time to reach the base.It will be about time for a sandwich.God Bless You."I  said.

These soldiers were giving their all  for our country.I could only give them a couple of meals.It seemed so little.
