When Frank(Statham) is fighting the bad guy on the plane near the end of the movie, the plane crashes and the front window shatters letting in the water when Statham jumps to the ground. A little after that, he picture clearly shows the plane sinking underwater. They are strangling each other at this point, yet the plane is barely filled with water, even though the front windows are out and they've been underwater for quite some time now. I'm pretty sure the plane would be flooded in seconds under these cicumstances. Also, when Statham knocks him out when the plane is under, the sun is shining clearly into the plane and on Statham's head. Isn't is dark under water?
