Relevance to Majestic Documents

According to the "Interplanetary Phenomenon Unit Summary, Intelligence Assessment": "…As to the bodies…it appears that none of the five crew members survived entry into our atmosphere due to unknown causes. Dr. Detlev Bronk has been asked to assist in the autopsy of one well preserved cadaver to be done by Major Charles E. Rea." The so-called "Eisenhower Briefing Document" identifies Bronk as a member of the Majestic 12 Group and involved with conducting alien autopsies.
