Question: Why did the drillers have to go through all the rigorous medical tests if the NASA doctors were going to pass them anyway, after most of them failed? According to the movie, Harry and his team were the best drillers on the planet, so it didn't seem like NASA had any other option considering the time constraints.
Answer: True, they failed to meet NASA's strict requirements. But the tests would at least determine if they could concievably survive the journey, if not maintian optimal health, etc. None of them lost consciousness for any extended periods in the course of the examinations, so they were passed.
Question: What are the military ranks of Tucker, Watts, and Halsey? It's stated that Sharpe & Davis are Colonels, and Lev is a Colonel in the Russian military. Gruber is referred to as Sergeant, but so far, the ranks of the last 3 weren't mentioned.
Answer: It is not mentioned in the movie. However, we can assume that Tucker and Watts are mid-grade officers. They would be below the commanding colonels, but above ensigns because of their flight status. Likely they are lieutenants or captains.
Question: It wasn't addressed in the movie, but did NASA intend for Lev Andropov to go on the mission, assuming the RSS didn't blow up? It seems odd that later on, he has his own pressure suit and spacesuit without any explanation.
Answer: No, he was not meant to join the team. The pressure suit and space suit he uses are spares brought along in case one of the others had a malfunction.

Question: In one scene of an overhead view of the White House, we can see that the flag on the roof is at half-mast. Why was the flag lowered?

Question: What did the Chinese guy mean when he did a thumbs up towards Harry on the oil rig?
