sunken 727, airline names?

[danware]

Hi,
I was diving in Mermet Springs in Illinois, this 727 was used in the movie US Marshalls. Apparently the "movie" paint has come off, and is showing other stuff, and/or no paint. In the pictures, when sunk was still in movie colors

But now is showing the name on the sides "Dauntless" Was this (or is) an airline, or somebody having fun at the bottom???

Thanks for your help,

Dan
