Two seats is all you need

"Although many pilots wouldn't buy a plane with fewer than four seats,
the
dirty little secret is that many if not most of us fly alone a lot. An
Arizona ranch hand has introduced a downright neighborly concept for
putting
like-minded pilots together that not only helps people out, but can
reduce
costs and boost the fun factor. Baldy (which he comes by honestly) Ivy
established PilotShareTheRide a year ago and so far hundreds of pilots
have
connected with one another for trips, training and rides around the
patch.
"It's about sharing the love of flying and if you can share expenses,
then
so much the better." Pilots planning a flight register it on the Web
site
and describe their itinerary. If someone happens to be going their way
(or
just wants to get up in the air), he or she e-mails the pilot in the
posting
and they sort out the details between themselves. Ivy stresses that
he's not
arranging flights (that would be Part 135 work), he's just providing a
kind
of pilot matchmaking service that leaves it up to the individuals to
decide
when and where they fly. There are about 4200 pilots signed up and, at
any
one time, about 500 flight postings."

Two seat aircraft should be the standard in sport aviation. And all
new aircraft under 4000 lb should be required to be certified in the
aerobatic category (in the case of production a/c) because training
pilots requires aerobatics. (Say otherwise, you are blowing manure.
That's why the Air Force BTT training programs do this-in beefed up
Citations.)

Limiting family trips in personal aircraft is good because that's what
generates get-home-itis and the kind of crashes that cause the alleged
liability problems.
