Tracy Morgan left Utah Monday ... with a breathing tube secured in his nose that was attached to an oxygen tank.
The photog asked Tracy just before he boarded the plane if diabetes or alcohol played a part in his 911 emergency at Sundance, when he fell into unconsciousness.
Tracy gave 2 answers:
Serious -- the altitude made him sick.
Funny -- "Superman ran into a little Kryptonite today."
