Now if the P-8 had done a barrel roll I'd be impressed.

I wonder what the largest aircraft to perform that was; Bob Hoover used to do a proper barrel in a Sabreliner.

I've seen the video of the Vulcan doing it's barrel role before, I've often wondered if a Victor could do one?

Regards.

In theory, any fixed-wing aircraft can do a properly-executed barrel roll. The stress on the airframe is minimal. However, I can understand Boeing management asking Tex Johnston to refrain from demonstrating it again on the 367-80. Their insurance premiums likely did not cover this kind of stunt.

You know, the 707 and Vulcan look like they're doing regular rolls, wherein the axis or centerline of the roll is the a/c's own axis, while a barrell roll the axis is a roll around a central point outsde the aircraft. The latter is what the J-11 did, with the P-8 as the central point.

I knew a pilot who flew Lancasters. Apparently one of the other pilots came up with a plan on how to conduct a barrel roll in he post-war years.

I'm a bit uncertain of the aerodynamics involved (if someone could explain this better - I'd appreciate it) - but apparently aileron control was expected to deteriorate at high angles of bank - so rapid throttle changes would be used to generate torque and help the airplane through the inverted phase.

I know that one Lancaster apparently went to 90 degrees bank after being zoomed by a reckless T-33 pilot.

The video of the Dash-80 (not strictly a 707) seems pretty clearly a barrel roll as you can see it climb as the roll is initiated. It was a nice gentle 1-g maneuver -- Tex Johnston said he could have left a glass of water on the flight deck and not spilled it.
