I have never heard of UTA Flight 772, but apparently it was a plane that crashed in Africa. If you want to see something cool though, look at this website. This is how they decided to commemorate the crash.
Yes, that is what you see when you go to the site on Google Maps. They made the whole thing by hand and large stones. Or something. You can go to the site and read all about it. I just think it looks cool as shit.
