I just had SENTRY 20 self ID as a Heavy E-3 with Wright Patterson METRO on 344.6 requesting WX for Tinker. He was at the Rosewood VORTAC on the 223 radial at 29,000' I had been hearing WIZARD ALPHA with HUNTRESS on 260.9 all afternoon. I assume that they were supporting the President's visit to South Bend, IN.
