The evidence Luigi Venditelli describes in the clip below as being "indisputible" and "100% proves something that Bob Lazar said in 1989" appears to be this photo taken by Gabriel Zeifman from an aircraft approximately 17 miles away from Papoose Lake. In the documentary, Venditelli says that "all you have to do is play with the contrast, play with the levels in the image. And if you look carefully in this version here where the contrast has been changed, that as we zoom, look what we see... You see them [the S4 hangars] clearly right there."
