My father survived a tour as a torpedo bomber pilot, started out on Hampdens and converted to Beaufighter half way through his tour. He considered his chances of survival as an instructor subsequently on the Beaufighter OTU to be worse than ops. The instructor on the Beaufighter crouched behind the pilot's seat and had no chance of taking over control. After 3 of his friends were killed whilst instructing engine failure on take-off he decided to take the option of transferring to the technical branch as an armaments officer, since they were attempting to find people with the right technical background at the time.
