Source in video dear brother look closely - its an EAM - i am sorry I assume most people here are aware of what Skymaster EAMs are.
For those who dont know:
Emergency Action Messages (EAMs) are messages transmitted from a ground station or an airborne command post (E-4B Nightwatch or E-6B Mercury (sometimes also called TACAMO)) to nuclear forces in the air or underwater (B-52s or nuclear capable submarines for example).
These messages can be anything from flight plans, weather information, etc. to launch orders, which you are highly unlikely to hear, as USAF comms go secure in times of emergencies or strikes against other countries from what we have been able to tell.
