Mick. I know its frustrating running a debunk site and being unable to do that, but there always has to be a first time. Why not 'man up' and concede that gerry has discovered something that does indeed require much more investigation as it appears to provide grounds to re-investigate NISTs contention that the girder spanning 79 -44 on floor 13 was the 'trigger' to the global collapse ? No-one will think any the less of you. In fact the reverse would happen, even within your own community. You would gain credibility as an honest and fair researcher.
