    No, this does not eliminate any of the above mentioned. Ir51 is in an
    engineering orbit with RAAN=300 deg. near epoch 01024. - the others were at
    215, 238 and 205 deg. at the time, ie about two planes away!
    
    Ir69 has the normal 14.34 MM, so not in engineering stand-by. This could
    indicate that it can not be controlled.
    
    Ir2 has MM=14.83, a much lower orbit than in stand-by, so it is probably
    decaying naturally.
