    I think we have overlooked the operational constraints :
    
    Using the day 265/271 elsets for USA 161/129 their separation would have
    increased to 2h 45m on, or soon after, Nov.14
    
    The MM of USA 129 could have reached 14.842 (with given B*, 14.833 if reduced by
    25% like USA116 (??) )
    
    AOP was just about 350 degrees for USA 129, 190 for USA 116 (225 for USA 161),
    so the two former could easily be adjusted in inclination.
    
    I think "we" should look for USA 116 and 161 with MM near 14.73, some 20 minutes
    apart, and USA 129 2h 40m before USA 161 near MM=14.72
