Does the whole plot take place on the night before Pearl Harbour? Given that her fight to become the first female fighter pilot probably takes longer than one evening, I’m assuming not.

Is this based on a true story? If so, I would strongly suggest adding “Based on the true story of a plucky…” and I would consider making the bit about Pearl Harbour the button on the logline. I guess it depends whether you show the attack on Pearl Harbour. I would probably suggest not since it’s been shown on film quite a few times already and I actually think ending the film with her happy in the knowledge that she’s achieved the unachievable… then the warning sirens sound.

I would consider having her as just “plucky” or just “indomitable” (although I would change this to “strong-willed” or similar… it’s a bit more accessible) as I’m not sure you need both. I would go with “strong-willed” personally, fwiw.

I like this. I really hope it is a true story as that would add a lot of weight to the logline. Interested to see your answers to my questions.
