Seriously, why are they banging on the cockpit door the entire time. That thing is designed to take a grenade blast, and you hammering on it with your fist is going to do nothing. I’m surprised that the terrorists didn’t plan for this...
Anyways, acting was great, cockpit lines for checklists and talking to ATC in the beginning was good, but not in the end. Copilot has more tools for this exact situation available, but didn’t use them? Good first half, but lacking a climax.
