On the eve of Pearl Harbor, a plucky and indomitable crop duster fights to become the first female fighter pilot in the Army Air Corps.

So what's the adventure given that she can't fight with the Big Boys?

The purpose of a logline is to state (succinctly) what the adventure is. (IOW: the story hook.) A logline is not a teaser. Loglines are pitches to movie makers; teasers are pitches to movie viewers -- different markets with different requirements and expectations. Movie makers want a clear, concise idea of what the adventure is.

No, Pearl Harbor is just an inciting event and reference point for the logline (WW2). We do not see Pearl Harbor and protagonist is not there. Do you feel 'As Pearl Harbor approaches...' would be better?

It is not a true story. It is historical fiction based on the Women Air Service Pilot program. They were the first women to fly for the US military, but they were not allowed in combat. (Women were only allowed in combat within past 5 years, actually.) The WASPs ferried aircraft around so the male pilots could go fight. My screenplay is about a WASP pilot who rebels against her station.

You are entirely correct on the historical fact. The protagonist is a Women Airforce Service Pilot (WASP). As for the rest, well...that's where the adventure lies. :c)
