Jack suggests that they were flying at roughly 40,000 feet when the plane hit an air pocket and crashed.

JACK [off camera at first]: We must have been at about 40,000 feet when it happened. Hit an air pocket. Dropped, maybe, 200 feet. The turbulence was: I blacked out.

Jack's first solo procedure was on a 16 year old girl.

JACK: Well, fear's sort of an odd thing. When I was in residency my first solo procedure was a spinal surgery on a 16 year old kid, a girl. And at the end, after 13 hours, I was closing her up and I, I accidentally ripped her dural sac, shredded the base of the spine where all the nerves come together, membrane as thin as tissue. And so it ripped open and the nerves just spilled out of her like angel hair pasta, spinal fluid flowing out of her and I: and the terror was just so crazy. So real. And I knew I had to deal with it. (He's crying). So I just made a choice. I'd let the fear in, let it take over, let it do its thing, but only for 5 seconds, that's all I was going to give it. So I started to count, 1, 2, 3, 4, 5. Then it was gone. I went back to work, sewed her up and she was fine.

Jack tells the pilot it's been 16 hours since they crashed..

PILOT: How long has it been?
JACK: 16 hours.
