The night of May 16th/17th this year marks the 80th Anniversary of 617 Squadron's attack on the Mohne, Eder and Sorpe Dams and as I had the Revell kit of the Lancaster B.III 'Dambuster' in my stash, courtesy of our eldest son, I thought it was time to build it. This is the 2009 release with new parts superceding the initial 2007 release and has 224 pieces, some of which aren't used, spread over nine sprues and a clear sprue. The twelve page instruction booklet has 65 build stages and the painting/marking instructions are for 3 aircraft: AJ-G, Wg.Cdr. Gibson's a/c, whose mine exploded short whilst attacking the Mohne, AJ-P, Flt,Sgt. Martin's a/c, whose mine missed the same dam and AJ-F, Flt.Sgt, Brown's a/c, whose mine hit and exploded and cracked the Sorpe Dam but failed to breach it as this was of an earthen construction unlike the steel and concrete of the Mohne and Sorpe. It will be this last a/c that I'm modelling. The squadron code AJ derives from Gibson's father Alexander James' initials.
