Sorry, no way to do spoilers in Voyager (please let me know if there are).

I didn’t expect a Rickroll in that

I guess for some folks this is all quite hilarious, but on the more serious tip:

From what I understand, the man was in late-stage cirrhosis, which heavily undermined both his blood-clotting ability and the integrity of his blood vessel walls. Evidently due to air pressure issues and the drinking of hot tea, two veins in his throat area burst, and it was like turning on a spigot, with no way to turn it off.

A pretty chilling cautionary tale against being a chronic alcoholic and flying, I guess.
