Pond Boss Forums INTRO Questions & Observations What Size Fries on June?

I re-read my post and realized I might have not been very clear. By unpressurized cabin, I mean one that is pressurized at an altitude higher than where your bag of fish were packed. As example, the bag for your fish may be packed at 2500 feet above sea level and sealed to maintain the O2 blanket. As an aircraft climbs, the cabin is pressurized to between 7000 and 8000 feet. The difference in pressure between 2500 feet and 8000 feet will cause the bag to expand and possibly rupture.
