Helping a fallen Pilot and a Vietnam Vet!!

Hi everyone John Clingman is a retired United former Cal pilot who immediately upon retirement had his health fall apart. John needed surgery to fix herniated discs in his neck. At his Pre Op physical they found he had advanced lung cancer. (He never smoked)They removed his right lung. In the process it was determined that his time in Vietnam had created damage to both his liver and Kidneys, Liver through Hep C and Kidneys from Agent orange. It was determined that he needed both a liver and Kidney transplant to have a long term solution. On July 24 John got the call that a transplant had come available after waiting more than 5 years. John and his wife Susan are facing massive hospital bills including a 20000 dollar life flight. If you could help in any way it would be appreciated!
