    I've seen a twilight pass, and the plasma trail isn't visible but the 
    shuttle is
    quite bright - brighter than a satellite. The *best* time is when the 
    comes in at night - the plasma trail is amazing.  But in Florida, they 
    have slowed enough so that none of these phenomena are visible, i.e.  too
    slow for a plasma trail, too low to be illuminated like a satellite, to 
    high to
    see like an airplane.
