"Drawing of J-Rod (an EBE or extraterrestrial biological entity) by mechanical engineer, Bill Uhouse, based on J-Rod's appearance dressed in a human man's shirt in 1970s or early 1980s at a conference table with physicist Edward Teller and eighteen scientists, including Uhouse. The project that linked Uhouse to J-Rod was a 'flying saucer simulator' to teach certain U.S. Air Force pilots to fly back-engineered, and/or actual, extraterrestrial craft."
