Footage of the 1955 707 prototype barrel roll

Barrel rolls are low G maneuvers so properly executed they shouldn't cause any of those things. My memory had the barrel roll as a 1G maneuver but wikipedia tells me it gets up to 2-3g (probably to enter/exit the maneuver). Were you thinking of an aileron roll? I mean, if a 707 could do it safely in 1955[1] modern airliners should do just fine. (not that I support routine barrel rolls on airliners...) [1] this video

this video See around 1:56. No significant heading or pitch changes that I can see, although it is difficult to tell because the camera is so far away.

there's film of Tex Johnston's Dash-80 barrel roll this video many years later, Boeing Chief Test Pilot John Cashman stated that just before he piloted the maiden flight of the Boeing 777 on Jun. 12, 1994, his last instructions from then Boeing President Phil Condit were “No rolls”. -- anecdote from link I wonder why "the suits" at Boeing are so against the barrel rolls? The pilots all agree it's not that big a deal, not dangerous, and anybody watching is going to love it. this article link says that the bigger the plane, the more dangerous because it will roll more slowly, and during parts of the roll particularly 90 degrees off "flat" there is no lift and you're going to be falling. I'm reminded of the tragic crash of a B-52 illustrating a similar circumstance, and this was the pilot's last flight before retiring link
