If the pilot was killed did anyone else have rudimentary knowledge of how to fly?Although a single control column and yoke, the Lanc could be fitted with a second yoke, and rudder pedals, if required, for conversion training, and, in current use, to comply with some rules.
The BBMF Lanc has this arrangement. In the pic above ( Post # 155 ), look at the right side of the control column, behind the yoke, and the attachment for a second control yoke "arm" can be seen.
The Lancaster at the Canadian Warplane Heritage Museum has dual controls, Veteran returns to Lancaster cockpit after 50 years. Which is a good thing as it flew across the Atlantic a few years back.
