In recent days we've noticed EAGLE has not been on ADSB when covering a Marine One arrival or the POTUS motorcade to Maryland. Not sure if that is a new thing, or just a glitch.
I've noticed the same thing Andrew. The EAGLEs (and some of the HMX-1 aircraft) still seem to generate an intermittent TIS-B target on ADSBExchange in the DCA, BWI and PHL terminal areas but you have to turn off the military filter to see it.
After requesting entry into P-56A from DCA Tower on 134.35, Park Police helo N11PP EAGLE ONE paints an intermittent TIS-B target as it surveys the Mall, Tidal Basin and White House area prior to a 'VIP Movement'.
NIGHTHAWK ONE is also lifting to enter P-56A, EAGLE has them in sight, will maintain visual separation. NIGHTHAWK ONE will become MARINE ONE when the President boards the aircraft.
NIGHTHAWK TWO and EIGHT lift off Anacostia shortly after MARINE ONE calls 'three minutes to liftoff' on the South Lawn.
Now, MARINE ONE airborne, 'will conduct mission as briefed' on the way to the Secret Service Training Center near Laurel, Maryland where EAGLE ONE is already waiting.
