Interesting Mode-S Call Sign Twist

For several years now it has been interesting to watch Mode-S intercepts to see what Mode-S call sign would be used by the USAF E-4B NAOC when the DoD SecDef is traveling and onboard. Now he is on a trip to the UK and his Mode-S calling isn't really one of those classic tactical calls this go around.

E-4B 75-0125 is transporting the SecDef and the Mode-S call sign being used is "OSD01"
