    Thanks to Paul Hirose for a most informative post. Just one thing
    bothers me:

    I don't understand how the earth's lumpy gravitation could affect
    inertia in a B2. I know it goes pretty fast, but it would have to get
    close to the speed of light for relativistic effects to become
    comparable to the drift of the ANS. Am I missing something?
