The UCD and pressure suit interior
Many have asked how it’s possible to use the “bathroom” when you’re locked inside a pressurized space suit. After all, it was crticially important for Felix to remain hydrated on his way up to the stratosphere.
A special diet was in force days ahead of the jump to eliminate the possibility of solid waste. A urine collection device or UCD was worn like a second skin inside the pressure suit. During urination the pressure suit would pressurize ever so slightly. That pressure pushed the liquid waste from the UCD down a tube through transfer connector hardware which extended down to a collection tank under Felix’s seat.
