1. Reminds me of the guy who died bungie jumping because of a simple error.
The bridge was, lets say 150' tall (dont' remember the exact hight, but we'll call it that). He went to get a bungie and the guy asked how long it had to be and he said 150'. Well, technically that's true - when the bungie is in a relaxed position. Expanded, it's a bit longer. Lets just say it was a one-way trip.
