Assumed launch time at 21:28:30 UT since the real launch time
has not been seen yet.  Thus the error in arrival time should
be assumed as plus/minus 30 seconds for early revs.  By real launch
time I mean the five second launch window.

Once again, Moscow observers have the first chance to see this around 
2242 UT.  Two revs later, London has a nearly overhead pass at about
0156 UT on 16 May.   Southbound passes occur in daylight and northbound
passes the satellites exit the shadow above 40 degrees north latitude.

This may be the last launch of five Iridiums on a Delta.  I believe one
more may show up as a possibility.
