Nice pics! This is my first post and I am a huge Lanc fan. Unfortunatley I miss seeing her in Edmonton as I had just got home from holidays and only heard that she was there on the 11:00 news and they just showed it taking off and leaving.
As for if there is any Lancs in the US the answer is yes. A private collector in Florida has a full plane and I think a partial airframe of another.
The Calgary Lancaster is only for display and is at a museum in the city. The Lancaster that catch22 is refering to is located in Nanton Alberta south of Calgary and yes they do have the 2 starboard engines the inside port engine being rebuilt. I don't believe they will ever make her airworthy again but they will have all four merlins running which is pretty cool IMHO.
Thanks for the post, nice pictures. I saw her fly in the early 90's at a Wings Over Houston airshow. It was exciting to see her fly. She is a regular at Thunder over Michigan if anyone wants to see her in action.
