Spoiler space.

Let me start by saying, I loved the movie. I don't know how 12 years later Paul and Vin look the same. They must use oil of olay or something. Anyway, my question is about the climax scene at the end with the plane. I will guess that a cargo plane needs a minimum flying speed or else it will stall. Lets just say that it's 100 MPH. That scene took about 20 minutes of the movie. Some quick math and the runway had to be at least 33 miles long! Still loved the movie though.
