You think maybe Ofek 7 spotted something... and here is something curious.. Barak became Defense Minister in June of 2007....and it was in this time frame that the strike was ordered and planning began.
I wonder if it is all connected.....hmmmmm.
At some point, that surveillance was handed over to or became visible to the Israelis.
Remember the NOKO vessels stopped on the High-seas by NATO. Everything that leaves is probably surveiled.
