Going Ballistic by Dorothy Grant

Michelle has adventures merely getting through an airport to a flight added to her schedule -- pushing the limits on her hours as a pilot.

And then, in midair, she gets shot. And remarkably enough, manages to land again, despite someone she is sure is a hijacker in her cockpit.

This ruins a false flag. After much running from danger, before and after an inquiry, she lands a job, and then the war arrives. . . .
