At the very end of the movie....
It was hard for me to tell but to me it APPEARED at the very end of the movie the scene was from where Denzel's character had the incident where he shot the wrong tank and all it looked like Meg's character was one of the chopper pilots that came in to rescue some of the soliders. If so, was that maybe some of the motivation he had for pursuing the truth so hard?
Or was it not from that scene or was it just a little shot of her flying the movie director gave us at the end of the movie? Or was it Denzel's character imagining her in a chopper flying?
