Thanks Outlander. I don't like to look up the answers, but I did to confirm this one. Turns out I was 1/2 a foot off..... the correct answer is precisely 52 1/2 feet.
But let me keep things going with a question.........
What Disney World attraction required the development of technology more advanced than that utilized by NASA at that time?
The natural guess, but sorry, that's not it! Actually, that ride employs technology specifically designed for astronaut training. But it wasn't more advanced than what NASA had at the time.
You got it, nice job! Believe it or not, the development of Test Track required incredible technological innovation that is now being employed by engineers outside of Disney!
Well I don't remember any more than four being visible. But of course all cars have steering wheels, and Test Track seats six. So I'm going to say that there are 10 wheels total.
(I could, of course, be omitting those on the roller track itself)
