I used to fly with a bloke called Tim, who flew Barons for the RFDS. He had a story ...
... pick up for a patient, with a nurse, and it was a hot day. Tim says to the nurse - "It's pretty hot, it'll be bumpy - is there any problem climbing to 10,000' to get above the bumps?"
Nurse says "No, not at all."
Tim climbs to 10,000' for a bit of smooth flying, only to be tapped on the shoulder by the nurse ...
"Faeces!" she "whispers" (at a semi-shout) in his ear.
"What!?" Tim says.
"FAECES!", the young nurse repeats. Tim looks back, and the patient is indeed VOMITING lumps of turd!
So, it turns out that the patient had a blocked bowel, and the only exit under the reduced pressure of 10,000' was UP, through the stomach and out the mouth.
When Tim questioned the nurse about the decision to climb, she said "Oh! I thought all aircraft were pressurised!"
