MOGUL was the cover up. Generals Jesse Marcel Jr & Sr. both explained on their deathbeds that the incident was indeed an ET craft that was covered up. General Haut did the same on his deathbed. So did about four other officers and one senior NCO.
You’re correct. They did.
I met Jesse Marcel Jr, before his death. His father showed him some debris in July of 47. It was not of this Earth. The government disinformation campaign has been very effective, and continues to this day. There are plenty of people posting on this page, who will go to their graves denying the reality of alien contact, even though THE GOVERNMENT ADMITS IT. There is a debate within the government, of how much to tell the public. The parts of our own government that are holding on to the craft and bodies, will not give up the crown jewels of power easily. Not even to Presidents, Senators, and Congressmen.
