giggling young

set up shop,
| the two adults at the scene decide ...these cow(boys)
don't have the

think they're in

which he

the maturity,
| and the where-with-all; but unfortunately, I don't have
the time."

E90 King Air, F90 King Air 200 King Air. The 300/350 is a
transport over 12,500 pounds and has to do it.

| Name one light twin that can take off on one engine.

| Note: a 737 is not considered a light twin.

Back in the early 1950s, AeroCommander flew a 500, piston
powered light twin from OKC to Washington, DC with the right
prop in the baggage area. Ike had one on the list of
approved executive travel planes. Ike was a pilot.

cycle

| The P&W PT6 is perhaps the most popular turboprop. It
uses
| air coupling between the power and reduction gear section.
| Makes it better in many ways, but there is a loss of
| efficiency.

Why can't you do this in real life?

ok, that's cheating too: Bob Hoover can do things in
a twin - or anything that flies for that matter -- that
are physically impossible.


Nobody can do things that are physically impossible.

Some pilots with some planes certainly can.

Tell me again how safe general aviation is supposed to be.
