Woman in the red car saw pieces of -cars- and steel parts of bridge “blowing up” into the air.

I hope the witness’ words are being taken out of context by the reporters.

Amazing pictures from the scene.....

There is an engineer on this thread right now. If you see this post would it be unusual for object to blow up when this bridge collapsed??

How incredibly awful.

The cynic in me, remembers all the people in Oklahoma City who saw a "middle-eastern" looking man running from the Alfred P. Murrah building too, but that angle was soon discarded. :o(

[I still care]

People are always a little excited when things like this happen.

Also, whenever there is a catastrophic failure there are lots of sounds and small events, some of which look like explosions. Remember all the people who swore they heard explosions with the World Trade? As things give, they “bang” - my guess is it is easy to confuse with an explosion.

No need to jump to conclusions here. Buildings and bridges are not new to sudden, catastrophic failure. This is just as easily an engineering problem.

I heard the witness say everything went up and there was a big puff of smoke.
