Fucking makes me sick.
Didn't realize a hospital was at the opposite corner of Wiltshire. Maybe thats the reason for hazmat suits? Tunnels connect? They could have been dropped by helicopter on the pad there easily without drawing attention, went down through the hospital, into tunnels/bunkers, and been extracted down where we witnessed with the blackhawk and other copters.
I'm very interested in how the hazmat men were only detected on extraction. They had to come in from somewhere…
Remember the scene in the Truman Show where he ALMOST makes it out of his bubble but they fake a nuclear plant meltdown to force him to stop?
Something interesting to consider about nuclear: it implies fascist control because of "muh saftey."
Just a thought…
