Another sleepy paper has picked up on this. We're talking quite the story, when the whole thing locks up, and they can't get it out because the rock has squeezed. That's because they haven't yet reached the "Mother of all rock squeeze", which is under the St. David's Gorge. The big guy says it's "demanding drilling conditions'. Yeah, this rock is as soft as cheese, to one of these machines!
The big trouble with these rock machines, is that there is no margin for error. You can design the machine to take 2" of squeeze, but 2.5" and the whole thing locks up! It's happened many times before in the world!
And speaking of techno-bureaucracy improvement, look at NASA! They've made a concerted effort to fight group think, by opening up the process, and bringing in external thinkers to trash their designs. Through this process, they found something like a dozen possible flaws and fixed them up! If only Canada would wake up!
