When you get the 404 ERROR and read the sentence below it click on "Industry Projects" then look for "By Category" section middle of the page, the UAV family is at the bottom of the list. Just did that 3 times and it works.
They might be updating articles or maintaining the site not unusual for these guys mostly happens around 1am EST but can happen at other times. Now it appears you can't link to any of the individual "projects" so go back to the bold and you'll just have to be patient. It will come back.

And can I now respectfully request that we get back to the purpose of this thread of why it's here and who it's for see
Post #1. Thank You!!
