In regards to Tex Johnston rolling the Dash 80 707 prototype, it was in Seattle over the annual hydrofoil races. Boeing CEO Bill Allen wanted to show his jet off to the world and asked Tex to do a flyby, but only a flyby. Tex says that he knew what the 707 was capable of and if it didn't fly, Boeing would be ruined, as they financed the plane out of their own pockets. He told his copilot that he wanted to show the world what the airplane could do and they would roll the plane. His copilot replied, "They're liable to fire you." Tex stated, "Possibly, but I don't think so." As the came in over the lake, Tex put the airplane into a roll, turned her around and came in and did another one, just so everyone knew they weren't dreaming. As he began the first roll, Bill Allen's mouth dropped. He nudged Larry Bell, CEO of Bell Aircraft, and asked if he could use some of Bell's heart pills, and was angered at Johnston's nerve to do something like that. Larry Bell laughed and said, "Bill, he just sold your airplane."
As Tex landed the Dash 80, he was called into Allen's office to explain himself. He entered the office and told Allen that the airplane was in a coordinated roll, the airplane held 1G at all times(which basically means you have have a cup of water sitting on the dashboard and it not spill) and never knew it was in a roll. He needed to explain the dynamics a little more to Allen. Bill Allen told him, "You know that, we NOW know that, don't do it again." Later that night, Tex was invited to Allen's house for dinner. As he entered, he was tackled by old friend and Eastern President Eddie Rickenbacker who told him something like, "You old scoundrel, why didn't tell me you were going to do that, I would have come with you; I wanted to be there!?"
Whether Bill Allen ever really forgave Tex for the roll or not is unknown.
But I maintain that anything with a wing can be rolled. A buddy of mine has rolled his Cessna 172 before, with me in it! Granted, you really have to work her to get her to keep decent altitude and you will lose a lot in the process, but it can be done. If you are in a bigger and faster airplane, its easier to sustain a coordinated roll.
I don't have a microwave, but I do have a clock that occasionally cooks shit.
