He might be referring to Grusch plus additional witnesses, mentioned by Mellon in a recent article by him on Politico:It has come to my attention through meetings with American officials that the United States Senate Select Committee on Intelligence and Senate Committee on Armed Services have been undertaking in-camera hearings with government and military subject matter experts on the recovery and exploitation of physical material from Unidentified Aerial Phenomena (UAP).
Source: https://www.politico.com/news/magazine/2023/06/03/ufo-crash-materials-intelligence-00100077Since AARO was established, I have referred four witnesses to them who claim to have knowledge of a secret U.S. government program involving the analysis and exploitation of materials recovered from off-world craft. Other sources who, rightly or wrongly do not trust AARO’s leadership, have also contacted me with additional details and information about an alleged secret U.S. government reverse engineering program. Some have supplied information to the intelligence community’s inspector general, others directly to staff of the congressional oversight committees.
I think he is referring to information on Wilbert Smith here, a senior radio engineer with the Canadian government Department of Transport at the time.As Minister of National Defense, you may not be aware Defense Research and Development Canada (DRDC) has participated in efforts to analyze UAP, which is publicly traceable to circa 1950.
From: Above Top Secret by Timothy Good, William Morrow & Company, ISBN 0-688-09202-0, 1988:
In a 1950 memo written by Smith (so two years before the aforementioned analysis), he states that he made some inquiries at the Canadian embassy in Washington and learned that:
During a recorded interview with C.W. Fitch and George Popovitch in November 1961, Wilbert Smith admitted that a number of fragments from UFOs had been recovered and analyzed by his research group, including one that had been shot from a UFO near Washington, DC in July 1952. Said Smith:
"I was informed that the disk was glowing and was about 2 feet in diameter. A glowing chunk flew off, and the pilot saw it glowing all the way to the ground. He radioed his report, and a ground party hurried to the scene. The thing was still glowing when they found it an hour later. The entire piece weight about a pound. The segment that was loaned to me was about 1/3 of that. It had been sawed off. …
There was iron rust -- the thing was in reality a matrix of magnesium orthosilicate. The matrix had great numbers -- thousands -- of 15-micron spheres scattered through it."
Smith was asked if he had returned the piece to the U.S. Air Force when he had completed his analysis. "Not the Air Force. Much higher than that," he replied. "The Central Intelligence Agency?" asked the interviewers. "I'm sorry, gentlemen, but I don't care to go beyond that point," said Smith. But he added, "I can say to you that it went to the hands of a highly classified group. You will have to solve that problem -- their identity -- for yourselves."
The memo is attached.
a. The matter is the most highly classified subject in the United States government, rating higher even than the H-bomb.
b. Flying saucers exist.
c. Their modus operandi is unknown, but a concentrated effort is being made by a small group headed by Dr. Vannevar Bush.
d. The entire matter is considered by the United States authorities to be of tremendous significance.
