The third photograph is thought to be the F-6e s/n 44-23725, delivered by the defector, or deserter if you prefer, Lt. Martin J. Monti of the USAAF to a German air base near Milan on 13th October 1944. The aircraft was first assigned to the Verschuchsverband which was the trials and research unit of the Luftwaffe high command, receiving German national insignia, yellow undersides, and the code T9+MK. Forth photograph. Next it went to Zirkus Rosarius which flew captured Allied aircraft to German bases so that they could be studied by pilots.At the end of the war it was discovered by advancing American troops at Schoengau, Austria. Fifth photograph. It was probably destroyed soon afterwards.
Mont was repatriated and court-martialled for stealing the F-5. Monti claimed that he had bailed out of the Lightning and had not delivered it to the Germans. Monti remained in the new USAF and was released in 1948 with the rank of sergeant. Upon his separation from the service, he was arrested by the FBI for treason, and put on trial. The FBI claimed they had found new information that Monti was aiding the Nazis with radio propaganda broadcasts. He was sentenced to of 28 years in a federal prison and was released in 1977. Some say this an overly-harsh sentence but William Joyce was hanged for not much more.
