Actually, with respect to maintaining one g into the seat and doing a
kind of roll, you can, or at least Newton says so,


Yeah, but only if you do it in a zero G environment, i.e, off the
planet's surface.



but I'm not sure
the airplane exists that has the control authority to do it. If you
search the groups you'll be able to find the analysis, but the short
form is this. The airplane has got to accelelerate downward at 1 G,
then pull a G in a coordinated bank. It'll roll, but it won't be
pretty, and the pilot will feel 1 G into the seat.

The diameter of the roll is something like 80 feet! Almost a snap
roll.

Also wrong.
