Franz Von Werra, a Nazi POW who was transfered to Canada to deter his multiple escapes and recaptures, escaped again in less than a month, traveling through the US, Mexico, Brazil, Spain and Italy to become the only Western held POW to return to combat. On 25 October 1941 Von Werra took off in Bf 109F-4 (W.Nr. 7285) on a practice flight. He suffered engine failure and crashed into the sea north of Vlissingen and was killed. His body was never found.
