NzTyphoon,
It is not my theory nor is that
one report the basis of the conclusion the United Kingdom aviation authority did not have stabilit and control standards.
Simply post the ARC standards used during the war. They will be written in a simliar fashion to EVERY other stability and control standard in the world.
They will define the acceptable qualities in an airplane.
Just like the NACA did!!
Here is the link to the UK ARC reports:
