They didn't bend safety rules on this launch. The fuel sensor issue that stopped the launch two weeks ago was never figured out. However, they removed all the fuel, checked and rechecked the sensors, and when the fuel was replaced, they didn't have any more problems. The original problem was just a fluke.
I'm so happy that it was a clean launch. It's such a joy to watch the shuttle lift off! I couldn't see it from home, although I have seen other launches from home before. I've even gone to Kennedy to see a launch live with my kids before. It was incredible.
Now pray that they'll remain safe, and land safely back home in 12 days.
