    Looking back at my 1996-1997 issue of Worldwide Satellite Launches, on
    page 162 I comment:-
    
    "There has been some speculation that 23932 at 57 deg might be some debris
    from the classified launch of USA 40 (1989-061B/20167) which was launched
    into this orbital inclination.   There is a great deal of debris
    catalogued from this launch (no orbital data issued) and the monthly
    Goddard Satellite Situation Report lists these objects as 'rocket body
    debris' from the USA 40 launch, suggesting that the rocket stage
    disintegrated in orbit."
    
    But what about the sets of data for the objects in 27-28 deg orbits ? -
    from the 1996 data surely that would have decayed by now, especially if it
    is debris.
