It seems a lot of posters here are not willing to accept a new aircraft design.
Speaking for myself, what I can "accept" and what I can approve may not be the same thing. I have test flown modified aircraft, which ultimately, I would not approve, and the aircraft was not approved in that configuration. Designs either must conform to the design requirements, or the design requirements must be adjusted to accommodate the innovative design. Aircraft which cannot demonstrate compliance to the requirements do not get approved for commercial use. This is an important aspect of the consideration of a new design.
