Panzon~ Been there! That's hilarious! Actually talked to a guy from a packing plant. Says the chip bags are designed to take altitudes of 8K ft, so that they could handle a pressurized airliner (with cabin altitude of 8K). That explains why it sounded like popcorn in my extra section to Point Hope, when I climbed up. A week later, I'm doing a charter, go into town, and the cash is selling those same bags of chips.... taped closed with scotch tape! And they were selling! When you have the munchies, you have the munchies, I guess.
Remember, if you have sodas explode on the aircraft, clean them up BEFORE you pull the airplane in the hangar. Easier to clean up when they're still frozen!
