USAF HF GCS.

This is coolbert::

ONLY at this very moment high priority [?] message traffic in response to the shoot-down of the FENCER Russian warplane that aircraft having violated Turkish airspace?
 

From MARCONI through Harry:

"The US frequencies in use by USAF HF GCS [High Frequency Global Communications System] (HFGCS)are very busy right now (1700 Zulu) sending the usual encrypted messages which they use. They are multiple messages and on as many as 4 or 5 frequencies at once This is unusual . . ."

Unusual YES!

Extraordinary circumstances require extraordinary effort with the obligatory unusual message traffic.
