@Ghost01: Why two eye(!)-witnesses? Has John Lear ever claimed that he has seen "S-4" himself?
As far as I can see, the whole "S-4" story is based only on Bob Lazar's tale. John Lear sure helped to "promote" it, but did he ever claim
first-hand knowledge on the subject?
Anyway, regarding the reliability of Lazar (multiple claims proven to be false) and Lear (way too deep into ridiculous conspiracy tales), there
is absolutely no reason to believe in the existence of "S-4" at Papoose Lake.
