Whoa, this is intense. I heard from 1 source that there's a No-fly zone in place, has anyone heard that? I also found a few articles from 2016 about a separate incident.
Information is hard to come by and i can't vouch for the accuracy of this website, but have a look.

Hanford for decades made plutonium for nuclear weapons and is now the largest depository of radioactive defense waste that must be cleaned.
Yes, I've heard there is also a no fly zone. With all of the military helicopters it also makes sense. This is really a total cover up. How can there be no radiation leaks if the tunnel is completely exposed? Also, everyone was evacuated. Apparently the location where the hole is located is where some high concentration is also located.
