Awesome, so could anyone buy a copy of the same images?  Which satellite
do you think happened to be taking images of the area with these ships
near the time the cables were broken?  Which company is selling that set of
images?


 Wouldn't it be reasonable that, when the break occurred, they used their
optical time domain reflectometer to compute the approximate location of the
break, and then just called around for whoever had the best images, or who
could quickly task the satellite to get an image?


Cable systems have these capabilities built in. In fact, before the
full break occurred they were highly likely to be receiving event data
indicating that there were problems occurring based on the movement of
the cable.
