My Grandfather was a B-17 Bomber Pilot, his first mission was D-Day 1944, he flew his 30 missions and made it back home to raise his family and work his arse off. Stayed in the USAF Reserves and retired a LTC. He rarely talked about what he saw or had to do during the war. I could tell even as a kid how it affected him.
He died peacefully in his sleep May 4, 1994. I miss him each and every day.
I usually go to the various family cemeteries and place jug of peonies at each family stone and a flag at the military members graves. It is something that I was brought up doing, my grandmother did it then, my mom, now my uncle and I do it.
