Authors write books so that they have an income. Some buy books based
on how much controvest they cause.  Thus some authors will pander to
this to increase their income.

it mentions that the Avro Air Car seems to have
just been a cover, and was not the real project, that Avro had in
mind to build. It had a much higher specced vehicle in mind, much
more ambitious than the Air Car - but of course it got canned, or
stopped in development, and somehow the Air Car was made to be some
fall guy for the entire project.

The Avro Aircar was one of a number of US Army projects through the 50s
and 60s that was trying to build an infantry battlefield 'air jeep'.
Other projects included rocket back packs, ducted fan flying platforms
and 'jeeps' such as VZ-7. The British had similar needs and models of a
couple of their projects were in the Museum of Army Transport in
Beverley.

None of the projects were successful. Some flew but most had inadequate
stability or control. In the case of the Aircar it was shaped as a disk
because it had a circular fan that was supposed to lift it vertically
and the body was roughly aerofoil so that it could provide lift when
flown forwards. It had nothing to do with 'anti-gravity' or 'nazi
superweapons'.

It failed to lift itself out of ground effect.  That is, it would work
as a hovercraft, but not as a VTOL aircraft. The few times they tried
to fly it showed it to be unstable and almost uncontrollable, as you
would expect (or I would) with a huge enclosed fan acting as a
gyroscope, even the engines were not handed so they too produced
unwanted gyroscope effects.

Details are in the book. Believe it or not.

At least there is the option.
