I am not an engineer, but I am in large scale commercial construction and I’m familiar with structural steel and concrete. There is a lot more to this than just slapping on some explosives like they show in the movies. This bridge DROPPED, amateur explosives would have blown OUT. The piles look untouched (which is the first place an amateur would have placed explosives). And NOBODY reported any odor from explosives.
Could terrorists have done this? YES. However, they would have needed demolition experts, structural engineers and original plans for the bridge. With this level of expertise, it would have made more sense to destroy an office building full of people.
Stop! Your making sense!
;)
Not to mention that it’s a heck of a lot easier to bring down an office building or shopping mall than it would be to rig a bridge.
Like I was trying to say before, I really don’t think this was anything more than a horrible case of structural damage.
For the most part I agree with your other comments except these. Do you really need demolition experts or just a terrorist training camp, the internet or the local mosque supplying the instruction on how best to blow up a bridge? We seemed to figure it out quite well during WWII after teaching boys pulled from the farm fields and just out of high schools of America and sending them off did we actually have the original plans for every bridge we came across and demolished in WWII because that is not how I read the history.
Give them the basics of how to bring a bridge down and most likely they can.
How did this bridge come down could not tell you until there is an investigation, and given past events like this we will not be told if it was brought down by explosives only that there was structure failure.
