>>14441303 PF REPORT - EVILI44 (Evil Eye 44-Obama) Out of Bloomington, IN circling Dupont, IN.
Identified as Sikorsky CH-53 Sea Stallion: this is a heavy lift helicopter.
Not really. As a planefag, I've seen SAM (Special Air Mission) callsigns change mid-CONUS. Also, SAM057, as I understand from other PF posts, had a shadow plane under MC057. I would assume the name changing was possibly done for "security" reasons.
IE, decoy….
