Air pressure in cargo hold during flight may wreck havoc on your guqin

After reading this article about water boiling at high altitudes, I begin to understand a little about the horror stories of cracked guqins that had been checked into the cargo hold. It would perhaps be better to hand carry your guqin into the cabin where the air pressure is nice and stable.

Quote from the article: "As the chamber reached around 25,000 feet, the technicians asked the crew member over the interphone if he was experiencing any sinus problems. If not, the steady climb to 85,000 feet continued. The first thing you noticed on the climb happened at 63,000 feet. A flask of warm water (98.6 degrees Fahrenheit or about 37 degree Celsius) placed inside the chamber slowly began to boil. By the time the chamber reached 70,000 feet, it was boiling rapidly, and at 80,000 feet the water was all gone-evaporated! The water was placed in the chamber to give you an appreciation of what could theoretically happen to your blood or other fluids without a pressure suit on."
