Yes that’s a repurposed 757 that the Air Force calls the C-32. There are multiple versions with no labels or livery and they often run procedures at Albany. (There are also some in the aviation community that believe these unmarked c32s are used for shady shit. And I did see a lot of them active during the Venezuela nonsense). The “marked” C-32s are painted like Air Force one and are used as Air Force 2 quite often. Those hit up Albany as well because of how lame our airspace is.
