Col. Paul Foster: What about our evidence? They've got to take notice of that.
Ed Straker: Evidence. What's it going to look like when Henderson claims that we manufactured it, just to get a space clearance program?
Col. Paul Foster: But we are right.
Ed Straker: Sometimes, Colonel, that's not quite enough.
In this episode the aliens with the help of 'turncoat' Turner have frozen a moment in time in which they will attack and destroy SHADO HQ. Everything and everyone is frozen in place - except for the guy in the background walking across the road during Straker's and Turner's 'car' chase in the 'Harlington/Straker' go carts.
