I'm not really sure if this qualifies as a B-movie or not, but I think it has that vibe. Also I'm not sure where else to put my review. It's sort of a cross between a monster movie and a war movie, but I'm not really comfortable putting it in either category. (I later started a category for disaster movies, and considered moving it there, but didn't because of the monster plot element.) It didn't make much money at the box office, but I think that's largely Covid-19's fault. I thought it was reasonably entertaining and possibly even kind of memorable, considering the fairly unique story. But it's not something I'd ever feel the need to watch again.

It's set during World War II, in 1943. A flight officer named Maude Garrett (Chloë Grace Moretz) fakes an order to board a B-17 bomber called The Fool's Errand, which is flying from New Zealand to Samoa. She brings with her a top secret package, but she's forced to leave it with one of the other crew members, Walter Quaid, while she's stuck in a gun turret. (For much of the movie, all we see is Garrett, and only hear the others over the comm system.) Aside from Quaid, all of the other crew members are quite sexist, at first not wanting to let her stay onboard at all, and later making lewd comments about her, not realizing she's listening on the comm. And as the flight progresses, they disbelieve most of what she has to say, even turning off her comm at one point. Of course, one thing she says is pretty hard to believe: she sees a gremlin tearing off parts of the plane, though remarkably the plane manages to stay in the air for most of the movie. She also is the first to see Japanese fighter planes coming after them, which the crew don't believe could have the range to reach them where they are. But eventually, they're forced to believe in both threats.

I don't want to say what eventually turns out to be in the secret package, but it's definitely surprising. Nor do I want to reveal any other major plot points or twists. So I guess there's nothing more for me to say. But I'm glad to have seen it.
