Navy SAR was quite limited in the ol' days as well, even though it would seem we were flush with helo's, crews, and $$$$..... My guess is it has something to do with the National SAR plan having USAF covering inland and USCG doing over-water.
A couple of friends of mine were early into a training night low-level from a coast-in point in western Oregon, enroute to the target @ Boardman after the low-level was complete. Long story short(er) ... they hit a tree crossing a ridgeline, flash/boom/punched, and spent the night on the ridge. One was on the ground with a broken leg; the other was hanging in a tree (a tall one) all night.
Kinda funny; the first communication (yelling) between them went something like this:
"Hey Joe" ... (pause)
"Yeah" ....
"You O.K." .... ?? (pause)
"Yeah, I'm O.K. ... how 'bout you" ... ???
"I think my leg's broken" ... (pause for @ a minute)
"Skipper's gonna be pissed"!!!

The next morning, the Air Force rescue guys in a C-130 up from Travis, I believe, found them via their beeper and PRC's --- followed by an AF SAR helo from somewhere -- one AF para-rescue guy was lowered into the trees and literally chopped his way down to hook up the guy hanging. The one with the broken leg got a "jungle penetrator" for his ride up.
Thank God for AF SAR ...
