I agree with Albatross and Hippo. Re the picture of RCAF Scoudouc, and assuming they're all Lancasters, there must be upward of a hundred on the field. I was convinced Evansb had got it with Greenwood. BTW Scoudouc is more like 46 10 N and 64 35 W.
Here's a Lancaster and Tiger Force website I've just found, in case you experts haven't been there already. The narrative suggests the Scoudouc picture is a stood-down, post-war gathering of the enormous Canadian commitment, before they were flown to Alberta to dry out.
