Very interesting story indeed.
I honestly think it's related.
There isn't much known information on this because the story went dark since being printed and nobody really knows anything else except that there are certain areas of the Grand canyon that are like Area 51.
Not to mention, David Hatcher Childress (Shilldress), who is also on Ancient Aliens and is considered the real life Indiana Jones, is part of it.
As you can see from this screenshot of a YT video that he was speaking about Kincaid, he was wearing this shirt with the all seeing eye.
I wish we knew more because I really feel that there is something definitely to this.
