I have read through the article with the following comments.

1) Stability is not a big issue with modern aircraft that are flown by
computers. The Airbus is unstable and the lowest level of control an
Airbus pilot has is to fly the thing like a car directly imputting
accelerations. If you bank lift is automatically adjusted to Sec
(theta).

2) The article mentions 32 degrees vertically. In fact lift is best
obtained by a vortex on the UPPER surface. As I have consistently
maintained only a proper CFD investigation can finally resolve this
issue.

3) Efficiency at 650km/h is still problematic CFD again required.


The article didn't get the interior of the Avro disc correct; the name
of the program was "SILVERBUG", and it relied on turning the entire
innards of the saucer into a gigantic flat turbojet:
