I happened upon some mil air activity on 126.2, in the West Point area. The call sign sounded like Shark 11 and Shark 12, along with a Rhino callsign in there. I only heard Shark 11 the clearest, the others came in at times but very faint and mostly unreadable. Then I heard Shark RTB on 132.75 and then over to Stewart Tower on 254.4. I heard nothing from the ground, but thats typical for the terrain in the area. I was wondering if anyone knew what type of craft they were, I know Rhino is typically associated with the F/A-18, but not sure.
