I got to see this film at a special screening on Remembrance Day 2019, in Hamilton (where I live, and where the Canadian Warplane Heritage Museum is located), amid a full house at one of our independent movie theaters. Some of the CWHM staff and Lancaster flight crew were there for a Q&A session afterward, along with the producer/director Morgan Elliott. They were great to listen to, the film was excellent, and it was just a great experience! In the audience, we also had a very old fellow who happened to be one of the original Lancaster pilots fron WWII -- he got a standing and very heartfelt ovation from all the rest of us there.
One thing I learned was that during WWII the Lancaster bombers were actually manufactured in Canada as well as the UK, so it's entirely appropriate that one of the only two remaining flying Lancasters resides here. That plane ("Vera") is the star of the show throughout, and we see all the events through her "eyes" and through the experience of her (civilian) pilots and flight crew. Vera has been lovingly restored to full operation by CWHM staff and volunteers, it's the plane that every visitor to the CWHM wants to see, and it's constantly in use for tourist flights -- it's a real icon around town that people here have really taken to heart. Its 3500-mile journey to England in 2014 to join the other working Lancaster for the Battle of Britain Memorial Flights, a tour of locations spanning 50 days, is a great story. One thing that leaps out from the screen is not just the magnificent shots from air and ground -- of which there's a full dose -- but also the reception they got from their English hosts. This all meant a LOT to them. Thousands of people flocked to every site in the tour, and "the Canadians are coming!" was the icing on the cake for their whole experience.
I also learned that there's a third Lancaster (callsign Just Jane) in England that is gradually getting closer towards full restoration as well. Maybe in a few years it will be possible to see all three flying in formation? I hope that some of the original pilots and crew (who were little more than boys in WWII) can live to see that. During the late stages of the War, hundreds of Lancasters would fly in a formation 10 miles wide, at night, with no lights and no radio; the collective noise from their classic Merlin engines shook the ground. 70 years later, one can only imagine.
Footnote: if you want to see more of Vera in the air, just google "Rick Mercer Report Lancaster" or search for that on YouTube, and you can see the segment where Rick rides with the crew aboard the Lancaster over Toronto, Niagara Falls, and the southern Ontario countryside. It's beautiful.
