People need to cut this movie a bit of slack. It's just meant to be fun. It's not meant to be anything else. Sure the history is bizarre. That's even pointed out in the movie, as they discuss the Battle of Dunkirk - in this movie it didn't turn out the way it actually turned out. So, somehow, history is a little bit different, which perhaps helps to explain a lot of what seem to be historical inaccuracies. They're not inaccurate. The timeline is just a little bit different. Folks need to stop fixating on that and accept the movie as sheer entertainment. From that perspective it worked quite well.
International Airlines Flight 42 from Dulles to Heathrow encounters a weird storm over the Atlantic, and when passing through it also somehow goes back in time - emerging over the French coast during a German bombing raid in 1940. Nobody knows how it happened, and it takes a while for everyone to be convinced that it has happened - but however it happened, it happened, and it's enjoyable enough to watch as the crew and passengers come to terms with their situation and try to develop a plan to get out of it alive.
It's a low budget, sci-fi movie about time travel featuring a largely little known cast. You have to know that going in to it and set your expectations accordingly. I think the rating this movie gets here (4.4 at the time of writing) is ridiculously low. I'm going to give it an 8 - not because it's a great movie - but because in spite of its limitations it accomplishes what it sets out to accomplish. It's fun and it entertains. I had no trouble watching it from beginning to end - which is more than I can say for a lot of big budget movies with mega-stars.
