USAF security patrolman who filed a contemporaneous witness statement, then years later claimed he touched a landed craft and received a binary-code 'download'.
Penniston's original statement is part of the documented record, but his most extraordinary claims (touching a warm, symbol-covered craft; a 2010-revealed binary code attributed to time travelers) emerged decades later and are disputed. His notebook bears an inconsistent date, and both Halt and Burroughs have contradicted the code/notebook narrative. He co-authored the 2014 book with Pope and Burroughs.
