This Me-163 was sabotaged while under construction by the forced labourers building it in Germany. A stone was found wedged next to the fuselage fuel tank and there was contaminated glue in the wing structure. Taken into service by JG 400 at Brandis around Aug 1944, it was captured by the British at Husum and shipped to Farnborough, then onwards to Canada. Loaned to the USAFM by the CNAM, Rockcliffe 1978-95 and to USAFM permanently in 1999. During restoration in Canada the inscriptions "Manufacture Ferme" (Plant closed) and "Mon coeur est en chomage" (My heart is not occupied) were discovered

Production Komets were not ready for operational use until July 1944 and only 279 had been delivered by the end of the war. The sole operational Komet group, JG 400, scored nine kills while losing 14 of its own aircraft. This example never flew and was most probably deliberately sabotaged by the French forced labourers that built it. The hulk was restored by the Canadian National Aviation Museum and acquired by the National Museum of the USAF for display in 1999.
