Please read  both of these short stories to learn the lesson.

World War II produced many heroes. One such man was  Lieutenant Commander Butch O'Hare. He was a fighter pilot assigned to an aircraft carrier Lexington in the  South Pacific.

One day his entire squadron was sent on a mission.  After he was airborne, he looked at his fuel gauge and  realized that someone had forgotten to top off his fuel tank. He would not have enough fuel to complete his  mission and get back to his ship. His flight leader told  him to return to the carrier. Reluctantly he dropped out  of formation and headed back to the fleet.

As he was returning to the mother ship, he saw something  that turned his blood cold. A squadron of Japanese  bombers were speeding their way toward the American  fleet. The American fighters were gone on a sortie and the  fleet was all but defenseless. He couldn't reach his squadron and bring them back in time to save the fleet. Nor, could he warn the fleet of the approaching danger. There was only one thing to do. He must somehow divert  them from the fleet.

Laying aside all thoughts of personal safety, he dove into the formation of Japanese planes. Wing-mounted 50  calibers blazed as he charged in, attacking one surprised enemy plane and then another. Butch weaved in and out of the now broken formation and fired at as many planes as possible until finally all his ammunition was spent.

Undaunted, he continued the assault. He dove at the planes, trying to at least clip off a wing or tail, in hopes of damaging as many enemy planes as possible and rendering  them unfit to fly. He was desperate to do anything he  could to keep them from reaching the American ships.

Finally, the exasperated Japanese squadron took off in another direction. Deeply relieved, Butch O'Hare and his tattered fighter limped back to the carrier. Upon arrival, he reported in and related the event surrounding his  return. The film from the camera mounted on his plane  told the tale. It showed the extent of Butch's daring  attempt to protect his fleet. He had destroyed five  enemy bombers. That was on February 20, 1942, and for  that action he became the Navy's first Ace of WWII and  the first Naval Aviator to win the Congressional Medal of  Honor.  A year later he was killed in aerial combat at the age of 29.  His home town would not allow the memory of that heroic action die. And today, O'Hare Airport in Chicago is named  in tribute to the courage of this great man. So the next time you're in O'Hare, visit his memorial with his statue and Medal of Honor. It is located between terminal 1 and 2. 

Story number two:

Some years earlier there was a man in Chicago called Easy  Eddie. At that time, Al Capone virtually owned the city.  Capone wasn't famous for anything heroic. His exploits  were anything but praiseworthy. He was, however,  notorious for enmeshing the city of Chicago in everything  from bootlegged booze and prostitution to murder.

Easy Eddie was Capone's lawyer and for a good reason.  He was very good! In fact, his skill at legal maneuvering  kept Big Al out of jail for a long time.

 To show his appreciation, Capone paid him very well. Not  only was the money big; Eddie got special dividends. For  instance, he and his family occupied a fenced-in mansion  with live-in help and all of the conveniences of the day.  The estate was so large that it filled an entire Chicago  city block. Yes, Eddie lived the high life of the Chicago  mob and gave little consideration to the atrocity that  went on around him.

Eddy did have one soft spot, however. He had a son that  he loved dearly. Eddy saw to it that his young son had the best of everything; clothes, cars, and a good education. Nothing was withheld. Price was no object.  And, despite his involvement with organized crime, Eddie  even tried to teach him right from wrong. Yes, Eddie  tried to teach his son to rise above his own sordid life.  He wanted him to be a better man than he was.

 Yet, with all his wealth and influence, there were two things  that Eddie couldn't give his son. Two things that Eddie sacrificed to the Capone mob that he could not pass on  to his beloved son - a good name and a good example.

One day, Easy Eddie reached a difficult decision.  Offering his son a good name was far more important  than all the riches he could lavish on him. He had to  rectify all the wrong that he had done. He would go to  the authorities and tell the truth about Scar-face Al  Capone. He would try to clean up his tarnished name and offer his son some semblance of integrity. To do  this he must testify against The Mob, and he knew that the cost would be great. But more than anything, he  wanted to be an example to his son. He wanted to do  his best to make restoration and hopefully have a good name to leave his son.

So, he testified. Within the year, Easy Eddie's life  ended in a blaze of gunfire on a lonely Chicago street.  He had given his son the greatest gift he had to offer  at the greatest price he would ever pay.

 What do these two stories have to do with one another?

Well, you see, Butch O'Hare was Easy Eddie's son.
