Apparently those involved in the UFO retrieval were to report their findings to scientists connected with the Research & Development Board. Sarbacher wrote to Steinman that he did talk to some of the people at the office about what was learned. According to Sarbacher, U.S. laboratories analyzed UFO hardware from the crashes and the pilots looked like certain insects observed on earth.
During a telephone interview with UFO researcher Stanton Friedman, Sarbacher was asked if he could recall anyone who did attend the meetings. Sarbacher gave enough clues to Friedman about a scientist he remembered being there that when Steinman cross-checked the information, the description fit the profile for Dr. Eric A. Walker, the former President of Penn State University.
Steinman said [that] he called Sarbacher to confirm his suspicions and [that] Sarbacher allegedly confirmed that Dr. Eric Walker, who was then Executive Secretary of the Research & Development Board, attended all the UFO meetings. When Cameron and I discovered [that] Dr. Walker might be involved, we set out to document what he may have learned from those meetings and what the Canadian and American governments were doing with this new-found knowledge.
Although our investigation started in 1987, William Steinman had been familiar with Walker's potential involvement since 1984. After several unproductive attempts to correspond with Walker by mail, Steinman phoned him on August 30, 1987. During the conversation, Steinman said that Walker indicated that he had known about MJ-12 since 1947 and that Steinman was delving into an area that you can do absolutely nothing about, and to drop it.
Cameron and I pursued the Walker connection for a book we were working on entitled UFOs, MJ-12, and the Government [subtitle: A Report on Government Involvement in UFO Crash Retrievals] up until 1991.
Walker was contacted by various UFO researchers from 1987-1990, and we were privy to the notes of these conversations in which Walker made some very candid remarks about MJ-12 and UFO crashes. In a conversation in 1990, Walker described MJ-12 as a 'handful of elite' and that he would know if you were invited into the group.
Besides the in-depth reporting on Walker, we investigated several other scientists who may have been involved, including Dr. Luis W. Alvarez, a Nobel Prize winner, who allegedly assisted in the recovery of a saucer in Mexico." credit Stig. Agermose
