However, I am skeptical about the entire story, if only because Bertha is depicted as resembling the circular scraping mouth of a lamprey fitted onto a giant fleshlight. This MAKES NO SENSE. Any fule kno that the canonical design for a tunnelling machine employs a helicoidal cone.
More likely the official story is a cover-up. History proves again and again that Bertha has probably run into a long-buried alien spaceship -- a relic of the Martian campaign to pass on their traits to our hominid ancestors -- and the authorities are stalling, worried that one wrong move will activate the ship's long-dormant psionic energies, with the resultant mass hysteria and genocidal rioting and cities on flame. This ALWAYS HAPPENS. It must be a tradition, or an old charter or something.

** I assume that Bertha is nuclear powered. If not, WHY NOT.
