9/11 Rescuer Saw Explosions Inside WTC 6 Lobby

Ground Zero EMT: " I tried to run into the lobby of 6 World Trade, but there were federal police... standing in the open doorways. As I tried to run in, they wouldn't let me, waving me out, telling me "You can't come in here, keep running." As I turned to start running west again, I saw a series of flashes around the ceiling of the lobby all going off one-by-one like the X-mass lights that "chase" in pattern... I immediately got the impression they were timed explosives. I have never thought they were anything else, not then, not now."

The cavernous hole left in the center of WTC 6 went from the ceiling of the 9 story building, past the multi-story basement, all the way down into the "Bathtub".
