Did I deny that debris damage caused the columns collapse in 7. No.
Did I say there was a CD, or argue that it was feasable in the towers. No.
My point was that you would only have to take out one floor, although true, (because that what happened with planes) was a bit pointless. I don't think you've understood what I have said because you are so polarised within this debate.
I myself from my first post have talked about Building 7, so I haven't 'switched tactic'.
Repeat, neither did I say it was a demolition charge that caused that one column to collapse in 7. I said that it was debris.
I did ask a slightly irrelevent question about whether one bomb could bring down 7.
But if those CD guys (MikeMC post 1428) had been on the ball they could have smashed that record by going into Building 7 and putting one charge in place.
