The black vans returned a body with a note attached. The story about Colorado Wing and Army UAVs (http://www.capvolunteernow.com/news/?colo_wing_aircrews_provide_support_for_army_uav_program&show=news&newsID=16325) is posted on the CAP Volunteer Now website.
An old but related CAP Talk thread:
Cool potential mission -- chasing UAVs (http://captalk.net/index.php?topic=4791.0) from 2008 where a proposal to chase Air National Guard UAVs was presented to the NEC. It appears to have gone nowhere.
Cool! I'm not a huge fan of RPAs personally, but it's good to see CAP plugged in with the military in a useful way.
