No, we're just talking about oxygen. They ran out of water days ago and may have been in freezing temperatures since Sunday. This being a rescue effort is them being extremely optimistic in case they were underestimated.

Possibly, but the loss of communications was a catastrophic failure on its own. Waiting so long to ask for help just sealed the deal. That is assuming that they didn't implode.

Yes, assuming it is even located. If the sub imploded and we don't find the remnants quickly, the sea life and detritus may well cover it up before we have a chance to find it. We only found the Titanic because it was very larger, it had gotten covered by all that stuff decades earlier.

If it's a recovery operation, it means a greatly reduced willingness to put anybody else's lives at risk. It also means that they can slow the process down a bit so that people don't get too fatigued.

@szbalazs2073 It's still possible that the sub is on the surface and wasn't seen. It wouldn't have much above the water as it's not designed to be a boat. But, that being said, in all likelihood they died days ago of one thing or another. But, even if it is on the surface at this point, they're probably dead from exposure or just running out of breathable air.
