Mossies.
Belatedly, in reply to the suggestion that producing Mosquitoes was more problematic than all-metal a/c, the answer is an emphatic 'no'. Different, yes, but not more difficult. The facts are all there. Production was well - dispersed, and Mosquitoes were also built in Australia & Canada with no big problem.
It's also well-worth pointing-out that most German night-fighteres couldn't even CATCH a Mosquito, much-less shoot it down. That's not saying it didn't happen of course.
There was a surprising amount of agreement that switching to a mainly Mosquito force would be logical, but there were a lot of (in)-vested interests too.......
I think the argument was pretty unasailable. That's not to say that the four-engined heavies didn't have a place for some roles of course.
BTW;- A chap I knew did several tours on Lanc's, and he said they were well aware of the Schragemuzik.
