    I thought they came in dead-stick? I don't think they use the thrusters in 
    the atmosphere, but I could be wrong. But isn't there sometimes a contrail 
    from the high-speed passage pressurizing the air and moisture condensing or 
    something like that? I seem to recall seeing some intermittant contrails on 
    previous landings (but then, I haven't had my coffee this am, so I may be 
    mistaken).
