The fall issue of Air and Space Power Journal focuses on Air Force SAR capabilities, primarily Combat SAR of course. However, CAP (and the ARCHER system) get a little shout out in the article on fixed wing SAR assets. That article promotes the use of more standard civil aircraft for SAR purposes in some situation where a little discretion is called for.
