That's a deep pull!
Marion Rudnyk claimed he found film from the Gemini flights hidden in the floor of the Jet Propulsion Laboratory (JPL) in Pasadena. The film had frames removed that supposedly would have shown UFOs, so in the usual UFOlogy logic the lack of evidence was proof of evidence. Even though the film had NO images of UFOs, the MiBs came and took it anyway because, again, the missing photos of the UFOs was proof that there were in fact photos of UFOs.

Probably because Lockheed Martin is the biggest defense contractor there is, and Lockheed had and still has the Skunk Works which created the U2, the SR71, the F117 and other advanced aircraft. But, Lockheed Martin has only existed since the mid '90s when they merged. But Northrup-Grumman has their own secret hanger near the Skunk Works at Edwards AFB where they developed the and B2 and B21 stealth bombers, so do they have their own UFO? Prior to Lockheed, EG&G was often the big boogie man defense contractor that was reverse engineering UFOs, likely because they were a big contractor at Los Alamos and Area 51.
That story doesn't work as well anymore, as EG&G was repeatedly bought sold and split up meaning the either the UFOs they had were moved around a number of times, or they're still at Area 51 in the possession of the US government. Coulthart made a big deal about a story he was told about EG&G maybe reverse engineering UFOs at Area 51 and a patch that supposedly was issued to people that worked on said UFOs. Or maybe to people that just worked at Area 51 for EG&G and knew about the UFOs or something like that as his claim changed with the telling's. Spoiler, the patch was for an EG&G radar group at Area 51, something folks here figured out.

Speaking of Coulthart:
He also made this dubious claim about a huge UFO hidden under a building, but of course he can't tell us where it is.
The thing here is, the shear logistics involved in building a structure to hide a humongous UFO means there are scores of architects, engineers and everyday trades people and construction workers, such that any one of them could be Coulthart's source. Meaning, he can tell us where this UFO is and settle all of this right now without giving up his source. But he doesn't. That's not his shtick, his thing is to just continue to tease and promise.
