Everyone has made some good points here.
RW did NOT always strike under the cover of darkness.
Regardless of where or when RW may have come upon Mariam, the possibility of such exists, regardless of how remote the possibility.
This snip here, shows that it WAS possible, that RW took Mariam, prior to leaving for CFB Alert on September 14,2009. We don't know what time the flight left for CFB Alert. It is reasonable, given the heavy schedules of those going on the trip, that is IS possible that it was an afternoon flight.
Given the following information, taken from CFB Trenton's newspaper, the latest possible flight, that the plane could have taken, from CFB Trenton, was 5 P.M. That is taking into consideration it was a 13 hour flight, and CFB Alert is 4 hours behind CFB Trenton in time. They arrived at CFB Alert at 2 a.m.
Time for RW to get from Toronto to Trenton for a 5 pm flight.
It took a 13-hour journey
in the back of a CC130
Hercules from Trenton, with
stops in Iqaluit and Thule Air
Force Base in Greenland,
before the visitors arrived at
CFS Alert at 2 a.m. the following
morning.
