nonsense.
good thing you didn't claim to be an engineer, too......

No, I am not a professional engineer. However, I did serve for many years as a demolitions expert on a Special Forces A-Team. I will say that suspension bridges are the toughest demolitions problem I have ever encountered. The main cables on the bridge are huge, and extremely difficult to secure effective charges to cut them. I shall not go into detail with the problem of dropping a tower, but it is a problem. You might recall the terrorists gave up on the Brooklyn Bridge, and I have no doubt that cutting the cable was the problem. Granted, one might be able to drop another section of the bridge, but unless one of the main cables is cut or one of the towers dropped the best you can hope for is a partial demolition.

Couldn't they get a small emergency vehicle --say an ambulance-- reinforce the suspension, pack it with explosives, and drive NEXT to the main cable, and then detonate?

As long as the charge was adequate, it doesn't seem to me totally necessary that the "charges" be *physically attached* to the cable, although obviously that would be best (for their purposes).

Of course, the girth of the cable is quite extraordinary...

here is what you wrote at post #45:

"Having worked with demolitions for many years msny years I can tell you it would take far more than 10 tons of high explosives to bring down the Mackinac Bridge."

1st....a "daisy cutter" is one example of what only 7 1/2 tons of HE will do.....and THAT is as an air burst, NOT even placed ON the target.

2nd....main cables.....genuine incendaries, NOT oxy/acetyl torch like the jokers in NY tried

3rd....main cables....acid

your resume' doesn't ring true (again)
