Stupidity: The highly trained commandos who knew everything about the NSA base and penetrated it during a perfectly planned operation through weapons and devices that pierce steel like butter, decided to stand outside the barn (so they knew something valuable was there) and its wooden door. It even has a direct line to the command center.
Stupidity: When the plane crashes and the family ducks into the small room off the main basement, powerful flames shoot all the way across the basement, up to the door that Ray closes just in time, but when he later opens it, nothing has burned, nothing is smouldering, not even fabric or paper, but the walls are scarred... as if from fire.
