They were not anywhere near the entrance to the Wpnsta.
Okay, I’m not familiar with the area. Just going by what another poster said. I think the speculation here is getting ridiculous. Authorities say they had pipe bombs that sounded like a firecracker when detonated, and now we’ve got FReepers suggesting they were planning to “take out” the entrance to a secure facility to get somebody out, and suggesting the pipe bombs were “shape charges” to be used to detonate uranium!
