There was also teams using ground-penetrating radar to see if they could find alternative routes or a location suitable for drilling (Chilean-miner style). That approach didn't pay off either, but I haven't heard of anyone complaining. Multiple approaches isn't a bad thing. They didn't put all their eggs in one basket. Musk just tried to provide another. If he was a little better at knowing when to run his mouth and when to keep it closed, the whole thing would be a non-issue. (for your facts: no the 'sub' wasn't used. And local police have said they've never had a single complaint about the caver. While it's impossible to prove a negative, we can safely say there's nothing publicly known about him to back up the slander.)
