In the second movie, pilot "disorientation" is no doubt created by the cockpit motion due to the displacement off the roll axis, giving him a different cue than he might expect because of the odd vertical g's and lateral swaying he no doubt experiences.
Probably loses a lot of airspeed also, so it might not be too popular if someone in the vicinity has evil intentions towards your longevity.
The off-axis nose motion is somewhat similar to the inertial-coupling that did in the short-finned F-100s, which pitched 90° to the line of flight and broke up when rolling. Extending the vertical on the F-100 fixed that.
And created the birth of ventral fins on other planes of that era.
I've watched contrails from the F-22 and others doing amazing feats of manuvering over the years at EAFB.
The prolonged " Harrier" for one... plane pitches up and stops any forward motion, then descends nose-high with no yaw for 1000's of feet. The engine contrail comes out of the exhaust pipe and then goes straight up as the plane sinks.
The purpose of this manuver isn't obvious, nor is there any observable benefit to losing all airspeed in a combat situation, but it sure interesting to see!
