Rocketship X-M/YMMV

Fridge Logic: The crew get their final medical check and hold a press conference only minutes before liftoff. Reporters accept the news that they can only print what's in the official handout without a murmur; a doubtful prospect even in The Fifties.
Stock Footage Failure: Footage of a V-2 rocket that looks nothing like the titular rocket was used for the launch sequence.
Values Dissonance: There's plenty of 50's sexist behaviour towards Dr Van Horn -- pilot Floyd Graham does the "What's a nice girl like you doing in a place like this?" routine, and thinks it's enough for a woman to Stay in the Kitchen. When Van Horn's fuel calculations differ from Dr Eckstrom's the latter overrules her and, when she gets upset over this arbitrary decision which could get them all killed, forgives her for "momentarily being a woman". However the film subverts this by having Van Horn turn out to be right after all -- compare this with the patronising view of female astronauts in Project Moonbase (1950) and Flight to Mars (1951).
