When I arrived Sunday afternoon (@2:30PM - 9 July 06). The escalators up/down from the center of T5 (right below where the DL CRC is) were blocaded and staffed by a TSA agent sitting in front of them. Is this the proverbial access to the tunnel(s). I can not recall an experience during my visits to T5 (at least in the last 4+ years) when that escalator was open. Does this go to both T4 & T6 (I think I recall reading that somewhere here on FT)?

In any case, it would seem the "pilot" may be "grounded" again.
