Best helicopter tours in Chattanooga around lookout mountain?

Visiting soon, and I want to do a helicopter tour for at least half hour. I saw adrenaline and wanted to hang glide, but the days I'm in town, they're not open.

I saw the guy on the interstate but it's like 2 minutes for 25 bucks so not interested in that.

Also, anyone check out Stir at the Choo Choo? Its been a decade since I last visited, so everything has been upgraded.
