Saw a show on the first 707 on the WINGS TV channel regarding
the barrel roll the test pilot did (unexpectedly) on the first
test flight of the dash-


Boeing 367-80, prototype for the KC-135 and B-707. No, it wasn't
a barrell roll despite what the test pilot, Tex Johnston said in
the interview. The following is quoted from an aerobatic web site.

From: http://acro.harvard.edu

The Barrel Roll is a not competition maneuver. The barrel roll
is a combination between a loop and a roll. You complete one loop
while completing one roll at the same time.
The flight path during a barrel roll has the shape of a horizontal
cork screw. Imagine a big barrel, with the airplanes wheels rolling
along the inside of the barrel in a cork screw path.
During a barrel roll, the pilot experiences always positive G's. The
maximum is about 2.5 to 3 G, the minimum about 0.5 G.
