0130 on 17 May 1943: ‘Cooler 6’ begins attack. Flt Lt Dave Shannon (RAAF) flying Lancaster Type 464 ED929/G, AJ-L (nicknamed “L for Leather”), makes the first run at the undefended Eder Dam during 617 Squadron’s Operation Chastise, watched by mission leader Wing Cdr Guy Gibson in AJ-G. The valley approach makes it extremely difficult to attain the tight release parameters and bomb aimer Flt Sgt Len Sumpter does not yet release the Upkeep revolving depth charge (“bouncing bomb”).
