I can’t believe they wouldn’t even let me hold a vote among the passengers about whether to try the loop.

    I think so. At the apex of the loop gravity balances centrifugal force, Fg = Fc, when going the minimal speed necessary to get through the loop. Fg = m g, Fc = m v^2 / r. So mass m drops out of the equation.
