    The distance seems about right for the range of the Trident II (about 7000 km) 
    from the general launch area I indicated.
    It would indicate I was wrong in my flightpath azimuth by some 40-45 degrees or 
    so, which is very well possible (I think you need obs from two localities, not 
    one, to get a proper result in this). I assume such a missile doesn't do a 
    dog-leg after launch?
