Curious too. I can’t even imagine driving a 16ton nail through hundreds of feet of hard rock and reinforced concrete.

- missedthecue 1y agoNot physically possible. You can get through hundreds of feet of loosely compacted soil and gravel but high performance concrete? 8-15m max. If they built the facility out of 30,000psi concrete, they'd be lucky to pen 4 meters with a direct hit, nevermind the 80m of limestone above it.
