Where 'bouts is Arlington?
Update:
"“There is debris in the Columbia river from those jets when they collided,” said KGW meteorologist Dave Salesky, who was driving along I-84 when the collision happened. “The air out here is thick with jet fuel over I-84.”"
Sounds bad.
About 136 miles east of Portland, right on the Columbia River (which is what separates Oregon from Washington). Very sparsely populated out in that area, fortunately.
Eastern Oregon, at the other end of I-84, near Pendleton.
Near the chemical weapons depot, just south of Hanford Nuclear Site.
