2nd Lt. Frank Luke, Jr. With 19 victories he was killed in action 29 Sept 1918. ***Side note for residents of Arizona, Luke AFB -- very close to where I used to live -- was named after him. ***
A boy left his bike chained to a tree when he went away to war in 1914. He never returned, leaving the tree no choice but to grow around the bike. Incredible that this bike has been there for 98 years now!
