Call sign FATTY76. USAF 757. Clandestine operations platform. This PF has caught this aircraft using a Delta Airlines call sign in the past. Looks to be headed for UK/Europe. It is PF's understanding that these USAF 757s are equipped for A2A refueling as well.

The 486th Flight Test Squadron is a secretive United States Air Force unit with a misleading designation, assigned to Eglin Air Force Base, Florida,[1][2] which is associated with activities of the U.S. State Department Foreign Emergency Support Team and Central Intelligence Agency Special Activities Center. The squadron motto is "Non semper ea sunt quae videntur" which translates as "Not always what they seem".[3] It is currently assigned to the 96th Test Wing,[citation needed] and operates a pair of Boeing C-32B Gatekeeper aircraft,[4][failed verification] on stand-by alert for special operations and intelligence missions world-wide.[5][unreliable source?] Official documents make it clear that operations fall under the aegis of Air Force Special Operations Command.[6] Of the two C-32B craft in existence, the 486th appears to fly the more clandestine craft, or on more clandestine missions, as the other operator of the C-32B, the 150th Special Operations Squadron of the New Jersey Air National Guard, denies the existence of a second aircraft and makes no mention of the 486th in public or internal documentation.

Here's what the American Special Ops website says about AFSOC:

United States Air Force Special Operations Command (AFSOC) operates a small number of Boeing C-32B passenger jet aircraft, providing global airlift for U.S. government crisis response activities. These may include U.S. State Department Foreign Emergency Support Teams (FEST), which deploy in response to terrorism incidents around the world. They may also fly in support of CIA Special Activities.

So we know that the plane at Shannon is used to respond to "terrorist incidents" and to support "CIA Special Activities". And we know that Shannon has had a recent history of supporting other CIA "special activities", in particular the kidnapping and torture (rendition) of prisoners.

The American Special Ops website goes on to say that C-32B aircraft have been associated with the 150th Special Operations Squadron out of Joint Base McGuire, NJ and the 486th Flight Test Squadron out of Elgin AFB, FL. And it says

These are highly secretive units, with little information publicly available about their activities. The aircraft have been spotted in a plain white paint scheme, with minimal markings. They appear to change serial numbers many times - no doubt an attempt to keep a low profile.
