The threat "WWII - Aircraft produced in large quantities that did not see combat - or very little" got me thinking about the flip-side of the question. What about non-combat aircraft that ended up seeing combat?
For this discussion, I'm not thinking of aircraft like the Wirraway which, although developed from a trainer, was actually intended to have a combat function. I'm thinking more about dedicated trainers/transport aircraft that, through force of circumstance, ended up in combat situations.
I have a few initial suggestions but will hold onto them until others have pondered the topic a wee bit.
