Congratulations, you have just successfully parroted the most common myth, and the big lie. Pancaking was tossed in the wastebasket back in 2003 or 04. I can't remember which year exactly, but its in there. Incidentally, it was introduced by the media in the first 25 minutes, 'on the scene', and it stuck...for awhile at least. But that's another scented trail, the introducing of 'facts' into the main media stream. I'll pass on that trail for now. Its not required to know, here and now.
Your first hypothesis on 'drilling' is out in left field.
Yes, i know my construction well, i was in the field for 20 years, commercial and res, but that's beside the point. Yes, i looked over the structural plans to satisfy myself, to gain understanding of loads, load points, and tie-ins of the floor trusses to see how the building was blown, but again, that's beside the point. Its not too complicated actually to understand, probably even to anyone without a building background. But of course you would have to spend a few hours learning the facts, which obviously, you have not done.
On the before page 5, (at 04-08-2009, 01:31 AM) I made a post, and pasted some links. Did you happen to read the post? If so, did you go to the links and look? Once you have done your homework on the subject, then come and talk to me. I made it very simple for anyone who is confused, and offered three info sources to pull from the human library and learn. That's enough help. Go do your own work. I did mine. Its all there. Gain the knowledge. Enlighten yourself. I submit, you will be in the dark until you do. Many people are more comfortable that way (kept in the dark). If they can't see it, it can't hurt them, etc.
