Al,
As part of a merry band of (very much amateur) historians studying bits and pieces of Bomber Command's contribution to the war and more specifically of family members who took part, one of the most important things to me is that the stories are not lost. Even if it's just for your family archive, please please please document them in some way.
The experiences were unique and absolutely fascinating - and even more so if it is a family member who took part.
On another note - I was at East Kirkby for a taxi run myself in April. There was a veteran rear gunner on our run. Andrew Panton (who rides crewman in the back of the aeroplane) said he'd try to fit our veteran friend in the turret if he could, but that he might have difficulty given the cramped confines. Andrew then turned and discovered that the old gunner had already installed himself in the turret, with far less difficulty than any of the younger participants on the day. I guess it never really leaves you...
