Potential location of UFO so big they had to build a structure over it (e.g. Coulthart)?

This is the Runit Dome, otherwise known as the Nuclear Coffin or Sarcophagus. I came across a post referencing this in a geography subreddit. This could potentially be what Ross Coulthart mentioned about a craft so big they had to build a building over it, and that it was not in the U.S.

It is 377 ft across and constructed of concrete. In the photo you can see people on the surface of the building, it is massive. If was built from 1977-1980 to contain the crater of a nuclear test known as the Cactus test, and its associated waste. It was constructed by the Department of Defense, Department of Energy, and the Department of the Interior. It was built on Runit Island in the Republic of the Marshall Islands. Nuclear tests occurred in that area from 1946 to 1958.

Military personnel who worked during construction have reported illness and cancer after working on the island. However the government denies any connection between the work and the illnesses, despite admitting to similar connections between illness and Agent Orange around this same time period 70s-80s. There are also growing concerns about the erosion and breakdown of the structure, leaving potential source of nuclear waste leaking during a storm.

Let’s step away from the prosaic explanation (Nuclear Waste) for now, and consider how this may be a candidate for Ross Coulthart’s giant ufo covered by a building.

1. It’s large. Look at the size of people on the roof compared to the dome. Transporting an object of similar size below, would be an enormous feat.

2. It is not on U.S. soil. It is located in the Marshall Islands.

3. The location (or at least the cover building) has international significance. Obviously it is of interest to the Marshallese people, and to the U.S. government because they built it. Even in the prosaic explanation, which is nuclear waste, the environmental catastrophe that would result from a leak into the Pacific is of worldwide significance.

4. It is related to nuclear weaponry. There is growing evidence to suggest a connection between nuclear weapons and UAP/NHI activity. We were conducting nuclear tests there. Potentially sometime after the tests (probably shortly before construction) the nuclear signatures like radioactivity attracted UAP and it crashed or it was shot down. Similarly, the presence of nuclear waste is a major deterrent for going there, which is perfect for covering something up.

5. The DoD and DoE are involved. Two of the big players in UAP lore were responsible for the construction of this. Given the prosaic explanation of nuclear waste, their involvement shouldn’t be surprising. However their motivations may be more than just environmental concerns.

6. Illnesses and cancer for workers. Obviously, exposure to nuclear waste can create cancer and various illnesses. However, Lue Elizondo has talked about the biological effects on people from UAP bearing similarity to radiation damage.

Now of course, we have to be realistic and consider that the prosaic explanation is supported by all these observations. However, these observations are also consistent with Ross Coulthart’s statements about a giant ufo, Lue Elizondo’s statements in biological effects, and with the players typically involved in UAP lore.

Based on these limited set of observations , it seems that we cannot rule out the possibility that this could be the location of a giant UAP with a building covered over it. But we cannot also say that it isn’t simply nuclear waste storage. Looking into this further, maybe through FOIA or declassified documents, might reveal information that would be diagnostic as to whether it is a UAP or not.
