    Re: Spotted a sextant

    I often use my old Mk3 (horizontally) for piloting around the Scilly Isles. 
    Very accurate. Much more so than using a hand bearing compass. (which would 
    not work on Mars anyway?).Also makes a good pelorus. Birch has a good chapter 
    on this in his "Plastic Sextants" book. If these guys are lost on Mars but 
    have accurate maps, they could probably find their way home with the good old 
    Mk3.

    I suspect that Professor Brian Cox, ex pop star, TV personality, professor of 
    physics at Manchester university, does not know what a sextant is for or how 
    to use it. All he knows is that it can be used to find out where you are. 
    There he is out on the surface of Mars somewhere (Utah desert) trying to find 
    his way back 'home'. Bless.
