Finding Jim Gray: Why Radar should be used first.

Feb 1Feb 2

There is nothing better than actual sighting given the right resolution as provided by Quickbird or Ikonos. If we have some confirmation that somehow the cross section of Tenacious to radar is none zero, then it was detected by radarsat if the boat was about that region. Here is the extent of the problem for the visible range)Quickbird, Ikonos, ER-2). Images are from Envisat of the region starting Feb 1. I am not saying we could not see anything, I am saying there is a high probability we did not have a shot of Tenacious even when flying over it.
