last year I attended a safety
seminar at the San Diego FSDO presented by an Edwards AFB test pilot
who pointed out the hazards in and around the R2508 complex. Adelanto
was mentioned for the high conentration of UAV activity with a strong
suggestion to keep your eyes outside the cockpit when you are in the
area. The footprint for their activty was significant.

Did the Edwards AFB test pilot happen to mention why they don't
confine their UAV operations to their not insignificant expanse of
Restricted areas?

It's always a good idea to keep a sharp lookout for conflicting
traffic. The Air Force conducted a study that indicated that only 3
or 4 seconds out of every 20 seconds should be spent on piloting the
aircraft; the rest should be spent scanning.
