Great Falls Sighting

Attempt to reconstruct the Great Falls Sighting as reflections off two airplanes. Arguments listed in the text constrain any involved airplanes to approximately the geometry shown and suggest that no bright reflection would be obtained from the aircraft during the filming. Nopnetheless, the arguments againts the aircraft hypothesis are inconclusive and the explanation depicted here can be described as tenable. (Adapted from diagrams by Baker, ref. 3).
