How amusing to read all of this stuff.
1) Testimony from people stating that they took note of 305 flying over their homes that night because it was flying so low and was so loud is pure BS. After all, 305 was flying at 10,000 feet with engines throttled back significantly. 10,000 feet is well above what jets departing or arriving into PDX would be flying in the area...even jets approaching PDX while flying over Ariel will normally be flying under 10,000 feet at that point.
2) The railroad tracks do not travel near or behind the Fazio's property. For those who care to look, they will note that the tracks are on the other side of Lake River. No one is honestly arguing that Cooper swam across a river to get to the "island" that Tena Bar is on only to hike another 2,3,4 or 5 miles to Tena Bar, are they? Moreover, no one is honestly arguing that Cooper jumped off the train at the terminal in Vancouver then walked 7 miles north to Tena Bar, only to turn around and hike another 7 miles back to Vancouver, are they?
