I remember a lecturer on my MSc course at Cranfield years ago recounting a story of the time he was advising an airline in an African country (I forget which one). He flew the line a couple of times and was readily invited to join the flight crew. On one occasion he mentioned he had a PPL and they let him fly the plane right down to approach. He handed the plane back but the pilot in the other seat but was “offered” the landing which he eventually managed to refuse, I seem to remember he still sat in the captain’s seat whilst the FO landed and the captain observed from the jump seat. The plane was full of passengers!
