Speaking as a person who lives where you can easily see any launch from Cape Canaveral with your bare eyes... Sorry, but really the shuttles were just done. They were amazing and advanced when they were fist built, but take off and re entry are very hard on everything to do with their structural, hull and systems' integrity. They were each essentially rebuilt....after every single mission. That is why there were so many of them in service, and yet launches were pretty infrequent. It took many months, and many millions of dollars, to make a shuttle space worthy again after it ran a mission.
