I have done a great deal of research on my uncle who was second pilot on a Wellington 1C (Z1110) of 101 Squadron which was shot down on the evening of 20th January 1942. The aircraft, from RAF Oakington near Cambridge, was one of three Wellingtons shot down by Ludwig Becker that night. Z1110 and its six crew went into the North Sea off Tershelling after attacking the docks at Emden. They were never found. From all my research, I am not clear whether Becker and Straub were in a Bf110 or a Do-215. I found another thread on this site about Becker and his aircraft later in 1942 and wondered if anybody can help me to clarify this? Thank you.
