(B) Pentagon brass duped by internal confusion and inter-branch secrets and rivalries, etc.

This is probably part of the answer. The witnesses seem to be entirely legitimate and honest in these cases, but they are misled by the shortcomings of the equipment, and by human psychology and fallibility.

However this fallibility is compounded by factions within the military and political hierarchy, people who have been misled by people like Elizondo, Reid, Bigelow, Davis and Puthoff, all of whom are encouraging the alien interpretation behind the scenes.
