I wonder why it is that JREFers know the names of all the logical fallacies but fail utterly when they try to apply them to real-life arguments.
In my opinion, the length of time the building had been standing before it collapsed is relevant to the context, particularly so in a thread with the title: "Gravity defying buildings?" You, on the other hand, have gone out of your way to comment on details you claim in the same post are not relevant at all. There's no need for me to attempt to justify my behaviour by comparing it to yours, because only you have behaved badly.
Truthers generally try to focus on the almost instantaneous dropping of the entire roofline and the 6.5 seconds it took for it to fall to the ground. Debunkers argue that we have to include the 7 previous seconds. Not happy with that fanciful doubling of the collapse time, triforcharity wants to include the 7 previous hours! Going back even further in time is inconvenient for the debunkers' argument, so it's assumed to be irrelevant.
