Corrected entry: Before flight 069 of NWA airlines is about to take off, the pilot tells his co-pilot to secure the cockpit cabin. The co-pilot locks 8-10 different locks on the cockpit door, similar to all the different locks you'd see on an apartment door in a bad neighborhood. A few scenes later, the owner of the airline walks right into the cockpit - none of the locks are still secured.

Correction: The co-pilot locks the cabin before take off. Nashawn Wade (Kevin Hart) doesn't enter the cockpit until after takeoff, allowing enough time for the doors to be unlocked off screen.
