Most people do not know the story behind the man after whom the O'Hare International Airport, Chicago was renamed. The man Edward Henry "Butch" O'Hare was the son of Edward Joseph O'Hare. Edward J. was a lawyer who worked closely with Al Capone before turning against Capone and helping convict him of tax evasion.
There is speculation that Edward J.'s actions were spurred by one or a combination of three reasons: to ensure that his son, Edawrd H. got into the Naval Academy, to set a good example, or to attempt to right his wrongs. Whatever reasons he had, his actions meant only one thing - gently easing the load on the spring. Eventually in 1939, he was shot dead but that didn't seem to matter much anymore because that same year, his son started flight training at the Naval Air Station Penascola in Florida. The son, Edward Henry "Butch" O'Hare went on to become one of the finest airmen in the US Navy during and after World War II. So fine was he that only 9 years and 10 months after his father's death, the Orchard Depot Airport in Chicago was renamed after him. What would have happened if his father had not unloaded the spring? My guess is that Edward H. would probably never have gone to Naval Academy, eventually Al Capone's syndicate would have been busted and Edward J. would probably still be working there and he would also have been incriminated.
Compressed springs are powerful but not only in the negative sense. In the next post I'll discuss the positive side to compressed springs and the aspect of stretched springs.
