Do you think the guys on the titanic submarine will be rescued?

For those who are unaware: A couple billionaires, a pilot, and one of the billionaires' son are currently stuck inside an extremely tiny sub a couple thousand meters under the sea (inside of the sub with the guys above).

They were supposed to dive down to the titanic, but lost connection about halfway down. They've been missing for the past 48 hours, and have 2 days until the oxygen in the sub runs out. Do you think they'll make it?
