As I was heading across the Desert a few monthes back, at the height of the Iraqi war, and wanting to cut through R2515 around Edwards Air Force Base, I had the following exchange with Joshua Approach...
Joshua Approach, Musketeer 123 requesting transition through R2515.
Joshua: Restricted area currently off limits, but let me talk to them at Edwards.
(About 20 seconds of dead air and then Joshua came back to me.)
Joshua: Musketeer 123, Proceed through the restricted area as requested, they need some practice on slow targets.
