If people don't have any kind of launch on their bucket list, they sure need to add one. I've only seen one, back in August 1984. It was the first launch of the Space Shuttle Discovery. It was a morning launch and my wife and I were watching 12 miles from the launch site. I don't know if it was the morning air, wind direction, or what exactly, but it got so loud, the vibrations so strong, it was like someone was beating on our chests with drum mallets!
My wife later became Director of a Challenger Learning Center here in Sacramento, the educational outreach that resulted from the Challenger explosion. During her decade plus of working with the Center she saw several shuttles launch, at least two from the grandstands just 3 miles from the launch pad. They were both afternoon launches and she said they were no where near as loud or intense as the first one we saw.
