On April 26, 1945, P-61B-10-NO, AAF SN 42-39559, was shot down by friendly fire at approximately 2130. It was from the 417th NFS, flying out of Giebelstadt, Germany, flying a night intruder mission in defense of the Ulm-Dillingen Bridgehead. The location of the crash site was recorded as "Vicinity Altishein, Germany T 30821"
The pilot was 2LT Thomas E. Cartmell USAAF (my uncle), flying his first combat mission. IDPF records suggest a catastrophic crash and burn. The radar operator was 2LT Hal Anderson, who bailed out before the crash but because of the low altitude, his parachute did not fully deploy and he was killed on impact. Tom is buried at the AMC in St. Avold, France, and Hal was buried in the U.S.
