    Indeed they do ... and what's more, TLEs for this supposedly
    decayed object continue to appear(!):
    UNK    Decayed: 2003/09/28
    1 27947U 03042J   03273.19089128  .00008481  00000-0  16870-2 0    43

    One possibility is confusion with 26212U 99057DA, also in a 98
    degree inclination orbit.  No elsets for 26212 have appeared since
    2003/09/28, and recent elsets showed the object near decay:
    CZ-4 DEB
    1 26212U 99057DA  03271.10461514 +.25981668 +32225-5 +69881-2 0 04418
