OldLurker and Basil,
You are both aware that UAS are flying in combat situations continually where dealing with intercepts is a little more common than your experience? Global Hawk's don't get shipped out they fly out to the remote areas they work in and yes through the ITCZ and in bad weather. Just because you don't understand how all these 'continuous decisions' are being made in the UAS world doesn't mean that they are not.
