Hi Mike,
Enjoyed reading about 620 sqn as my father Flight Sgt Frank Edward Reed was a member of Sterling EH945 That was shot down over Hanover 27th Sept 1943.
only 2 years ago his grave was located at Hanover where i stood next to his grave for the very 1st time.
Like you i am some one who enjoys marathon challenges however mine are through walking see
www.walkyourowntalk.yolasite.com Next year i plan to walk from Chedburgh to Hanover in memory him and his crew.
Flight Sgt F Emery, Flight Sgt H R Kerslake, Sgt W Howes, Sgt W Ewanko,Sgt Cavey and Sgt J L Perry.
I currently livein NZ but will be coming home Jan 25th next year.
Any advise would be welcome
NIGEL.
