I note also that the real estate development where he parks the plane
has a very fragile runway. I wonder how he manages to take off and
land on a runway that is composed of only two inches of asphalt.

I can assure you that the runway is MUCH more substantial than
that. In the mid-80s. I was employed by the previous owner of
the development, Arthur Jones, inventor and manufacturer of the
Nautalis line of exercise equipment. He owned three B-707s which
we flew from that runway before it was lengthened to its present
length.

Do a 'google' for Terry Jones and Jumbolair....she flew as copilot
for me once. I was hired to train her for a B-707 Type Rating, but
quit before that happened...her husband was impossible to work for.
