Just FYI -- A properly flown barrel roll is a 1g maneuver, which means that the passengers wouldn't even spill their drinks. Any airplane can do a barrel roll.

And is also an incredibly complex piece of equipment that relies on thousands of parts (some of which can fail silently and lead to incorrect output), has zero common sense or reasoning capability, and is only as good as the program it's running.

I drive a stick... I'd take your bet. Only stipulation is that I get a compass.

You're wrong. There is no physical connection at all between the cockpit and the control surfaces. EVERYTHING is filtered through a computer. And I have no idea where you got the idea that the computer will automatically "guess" at the correct airspeed in the event of a sensor failure... In a Boeing, the pilot is in command. In an airbus, the pilot must ask politely...
