 "Engineers were in fact initially surprised by the collapses[18][19][20] and at least one considered explosives as a possible explanation.[21] "  I think this line leaves the impression that engineers were surprised by the collapses after the planes struck, when, I believe, the articles themselves expressed surprise at 9/11 generally.  Additionally, we should be clear that when we say that engineers considered explosives as an explanation, they considered the explanation and found it to be absurd.
