An E-4B just flew over my Alexandria, Virginia, observation bunker on a departure route from JB Andrews. [View all]
TITAN29, https://globe.adsbexchange.com/?icao=adfeb3
Registration number 73-1676, so it's getting back there.
It had a distinctive and rather loud sound. I knew it was something I don't see every day.
Wikipedia says this is the oldest one.

Variants
E-4A
Three aircraft produced (s/n 73-1676, 73-1677, and 74-0787), powered by Pratt & Whitney JT9D-7A (first two aircraft) or General Electric CF6-50E2 (third aircraft) turbofan engines. No bulge to house equipment on top of fuselage. These were later converted to E-4Bs.

No one's sent me a reverse 911 call to announce the start of WWIII, so this seems like a routine training flight.
Probably.
