Gee, the old "The bomb has been damaged so someone will have to detonate it manually" cliche. That's only been used in about 1000 movies...

I liked how when the people were looking across the water-filled gap, it looked like it was about a mile across, but the satelite images showed a gap of about 50 miles or more.

I'm by no means a physics expert, but I think the support disapearing under the cars made them fall at a different rate. If you throw something up in the air, you'll notice it hangs there for a moment before falling to Earth. Same principal with the cars, I imagine.

I don't know if I'm what anyone would call a Physics Expert, but I have did take graduate courses in Physics, and my specialty in Chemistry is kind of a cross between Physics and Chemistry. I've also taught Physics at the college level, a few years back.

As far as the beam falling out from under the bridge causing the cars to 'float' abov e the bridge...?

Nah.  Not at all. The only force pulling down on the bridge or the cars is gravity, and everything falls with the same acceleration (ignoring air resistance, which in this case would not matter ....the cars would not have higher air resistance than the bridge itself, the cars are behind the bridge).

What you are talking about seeing things 'hang' in the air when you throw 'em up is due to the acceleration due to gravity slowing it down, until it stops, then starts to fall.  The acceleration is downward, the initial velocity is upward.   The final velocity is downward.
