Wow, that's amazing. Thank God they had an airplane to escape in.
But the whole premise is unrealistic. As a pilot, let me lay out how it really works starting with your arrival at the airport:
Find your gate key or punch in your number code - 10 seconds
Wait for the gate to open - 30 seconds
Wait for the gate to close behind you - 20 seconds
Drive to the hangar - 2.5 minutes
Unlock the hangar and open the doors - 1.5 minutes
Remove wheel chocks, any ropes, miscellaneous covers on the plane - 2 minutes
Pull airplane out of hangar - 1.5 minutes
Check fuel - 1 minute
Find phone number and call fuel truck - 1.5 minutes
Wait for fuel truck - 15 minutes
Fuel plane - 8 minutes
Drain fuel / water check - 1 minutes
Pre-taxi checks, start engines - 1.5 minutes
Listen to ATIS - 1 minute
Call ground control, get taxi clearance - 1 minute
Taxi to runway - 2 minutes
Call tower for takeoff clearance - 1 minute
Take off - well, that was in the movie, plus engine temps and pressures should be up and checked already
Already we're over 40 minutes.
And that was skipping bullsh!tt1ng with the guys in the terminal, putting air in the tires, performing a standard preflight check, doing engine runups, or lots of other things.
See? That whole movie is simply ridiculous just based on an analysis of using an airplane to escape disaster.
Sheesh, they should have at least talked to a pilot before putting that crap on film!
I might rent it
