It also has been spotted recently broadcasting only an ICAO hex code and no other identifying information. Today it only lacks a call sign.
99-6143 Boeing C-32B (757-23A) (MSN 25494/611) of 486th Flight Test Squadron, US Air Force, at Perth Airport – Sat 31 October 2015. This aircraft is assigned to a secret unit which operates as part of the USAF Special Operations Command and the United States Department of State Foreign Emergency Support Team, which are on stand-by at a moment’s notice to deploy US civilian intelligence and diplomatic personnel to the scenes of terrorist incidents and world crises. It may also be used with the Special Activities Division of the Central Intelligence Agency (CIA). The squadron motto is “Non semper ea sunt quae videntur” (“Not always what they seem”). This is one of two C-32B aircraft with the unit, but it is often painted with different serial numbers, being reported as 98–6006, 99–6143, 00–9001 and 02-5001. The C-32s are based at Eglin Air Force Base in Florida and it is believed that the test squadron designation was chosen to blend in with the flight test operations that are conducted at Eglin. It arrived at 11.25am on Thursday 29 October 2015, using the callsign ‘NORA 11’, arriving from Pago Pago (Western American Samoa) via Brisbane. It departed at 9.10am on Sat 31 October 2015 as NORA 11 back to Brisbane. The light trail in the background was from Jetstar flight JQ968 landing on runway 24. Photo © Marcus Graff

Squadron Patch 486th Flight Test Wing sm.gif
The 486th Flight Test Squadron is a secretive unit, with a somewhat misleading designation, assigned to Eglin Air Force Base, Florida,[1] and which is associated with United States Department of State Foreign Emergency Support Team activities. The squadron motto is "Non semper ea sunt quae videntur" which translates as "Not always what they seem".[2] It was apparently assigned to the 227th Special Operations Flight, later redesignated the 150th Special Operations Squadron, 108th Wing, New Jersey Air National Guard, McGuire Air Force Base, New Jersey, but is currently assigned to the 46th Test Wing at Eglin, and operates a pair of Boeing C-32B or Boeing 757-23A aircraft,[3] on stand-by alert for special operations and intelligence missions world-wide.[4] Official documents make it clear that operations fall under the aegis of Air Force Special Operations Command.[5]
