You probably recognize the name Mark Harmon, he's been a famous actor for about 4 decades. But, have you heard about his dad? (thank you Steve!)

Thomas Harmon played college football as a halfback for the Michigan Wolverines from 1938 to 1940. He led the nation in scoring and was a consensus All-American in both 1939 and 1940 and won the Heisman Trophy, the Maxwell Award, and the AP Athlete of the Year award in 1940. He was inducted into the College Football Hall of Fame in 1954.

During World War II, Harmon served as a pilot in the U.S. Army Air Forces. In April 1943, he was the sole survivor of the crash of a bomber he piloted in South America en route to North Africa. 

Six months later, while flying a P-38 Lightning, he was shot down in a dogfight with Japanese Zeros near Jiujiang in China.

After the war, Harmon played two seasons of professional football for the Los Angeles Rams and had the longest run from scrimmage during the 1946 NFL season. He later pursued a career in sports broadcasting and was the play-by-play announcer for the first televised Rose Bowl in the late 1940s and worked for CBS from 1950 to 1962. He later hosted a 10-minute daily sports show on the ABC radio network in the 1960s and worked as the sports anchor on the KTLA nightly news from 1958 to 1964.

In April 1943, an Army bomber piloted by Harmon, and nicknamed "Old 98" after Harmon's football jersey number, crashed into the South American jungle while en route to North Africa. Harmon reported that he had been flying through heavy rain turbulence for two hours. When Harmon tried to fly the plane to an opening in the weather, there was a sharp crack from the right wing and engine, and Harmon was unable to pull the plane from a steep dive. 

After ordering his crew to bail out, Harmon parachuted from the plane at 1,500 feet. He ended up in a tree 20 yards from where his plane crashed. Out of a crew of six, Harmon was the sole survivor of the crash and spent several days working his way through jungle and swamp. He ultimately came upon natives in Dutch Guiana who escorted him in a dugout canoe to a village, where he was taken by outrigger canoe to a base of the Antilles Air Command.

After a brief assignment as a Lockheed P-38 Lightning pilot in North Africa, Harmon was assigned to duty with the 449th Fighter Interceptor Squadron in China in the summer of 1943. In October of that year, while escorting bombers on a low-level mission over Jiujiang, Harmon's P-38 was shot down over the Yangtze River by a Japanese Zero during a dogfight. According to some accounts, Harmon shot down two Zeros in a dogfight over the Jiujiang docks and warehouses.

 Harmon was forced to bail out into Japanese-occupied China. He was later rescued by anti-Japanese Chinese guerrillas. Harmon was awarded the Purple Heart and the Silver Star for his actions with the 449th Fighter Squadron.

Harmon saved his silk parachute from the crash of his P-38, and it was used as the material for his wife's wedding dress.
