Structural Engineer On the Fallacies of Movie Bridge Destruction (hackaday.com)
szczys writes: Suspension bridges like the Golden Gate Bridge and the Brooklyn Bridge are favorite victims for movie makers but are almost always shown to perform in violation of the laws of physics. Structural Engineer Alex Weinberg couldn't stay silent any longer. He covers how bridge collapses in several major films should have looked. The biggest offender? Christopher Nolan's The Dark Knight Rises.
Next they will be telling us that X-Wing fights can't really bank in space and don't make that "rrrrrrrrrrrrrraaaaaararrarrr" noise.
Pretty much everything in every movie is not realistic. Why should blowing up bridges be any different.
Go see movie. Suspend your disbelief. Enjoy it. Go home. Get on with the rest of your life instead of sitting around with nerds over analyzing everything.
If you have a few minutes to waste, or are passionate about suspension bridge structural integrity, well worth a read.
Never let a lack of data get in the way of a good rant.
