Yes the last 3 cars are backwards! Astroworld used to do this for their version of fearfest and eventually just did it year round. XLR-8 was the 2nd Arrow suspended coaster ever built (the first being The Bat at Kings Island). XLR-8 featured two lift hills and only went about 38 mph, my drive to work is probably more exciting than XLR-8. This could probably be done with Top Gun, that would be pretty cool if they did do that! Last I heard XLR-8 had been sold for about 7000 dollars, dont know how true that is but it was from a friend who went to the astroworld rides auction. My father is from Houston and used to work there as a kid, he said that park used to be so beautiful and nice. We went there last spring and Six Flags took horrible care of it, judging from the pictures Six Flags really let it go down hill.
