# Info on Space Shuttle Autolanding Data Base

    1. Title: Space Shuttle Autolanding Domain

    2. Sources:
        (a) Original source: unknown
            -- NASA: Mr. Roger Burke's autolander design team
        (b) Donor: Bojan Cestnik
                    Jozef Stefan Institute
                    Jamova 39
                    61000 Ljubljana

                  Half-Century Survey, 466-489, Oxford University Press.

    4. Relevant Information:
         This is a tiny database.  Michie reports that Burke's group used
         RULEMASTER to generate comprehendable rules for determining
         the conditions under which an autolanding would be preferable to
         manual control of the spacecraft.
