It’s not looking good for the miners in Pennsylvania–the drill that they were using to make a new shaft broke its bit, and they’re losing valuable time flying in a new one (one wonders why they didn’t have a backup already there).

But it seems to me that there’s another problem that I haven’t seen discussed. They’re pumping compressed air in to force back the water. Presumably the air pressure down there is pretty high, and they’ve been down there a long time, so they’ve got to be pretty nitrogen saturated. When they rescue them, how are they going to keep them from bending, perhaps fatally, when they come up to surface pressure? Are they just going to medivac them to the nearest hyperbaric chamber?
