When It is "NOT" escorted does it use TCAS??

This would be one more reason for those of us that still do not have transponders
to get that taken care of.

I don't know if it has TCAS, but it's in a Restricted area when it's not
being escorted, so I assume all the pertinent parties in the area are
aware of each other, even without TCAS.

The aviation editor on a local TV channel tonight had a story on them,
and reported that it is flying at 19,000 feet in "positive control airspace".
(I guess he figured that would be less confusing on the 10 pm news than
"class A airspace".)
