How did the fake FBI agent know?
Just watched the film. What I could not figure out is how did the fake FBI agent know that the plane had crashed near there in the first place?
Also, if he had a hunch that the plane was near there , why go to the police to help find it? It was only a bit of luck that the police officer remembered that the brothers mentioned a plane and therefore able to find it. Going near the police pretending to be FBI should have been the last thing he would have done.
