Nena Wiley's book America's Drug Enforcement Air Force (Motorbooks circa 1990) looking at the various air branches of the then US Customs Service and USCG, and DoD assets trying to combat the drugs coming in by air and sea. In the last few chapters dedicated to the DoD - NORAD and ARNG and ANG, theres mention of the 163rd TRS (now equipped with Predator after changeover from KC-135R) then equipped with RF-4 and how they assisted local law enforcement from US Customs Service, US Border Patrol and prob CHP etc etc.
And back to topic, didnt a while back, maybe 10 or 15 years ago, some girl went missing in Norfolk and a
PR.9 was scrambled from Marham to help the local constabularly?
