1. A waste handling system comprising: a urinal having a urinal outlet;first and second urine storage containers; anda distribution system fluidly interconnecting the urinal to the first and second urine storage containers, the distribution system includes a switching system selectively fluidly connecting the urinal outlet to at least one of the first and second urinal storage containers in response to an input, wherein the switching system includes a flow diverter valve, and the input corresponds to a command signal to the flow diverter valve, the command signal commanding the flow diverter valve between first and second positions, the first position corresponding to a fluid connection between the first urine storage container and the urinal while blocking a fluid connection between the second urine storage container and the urinal; and the second position corresponding to a fluid connection between the second urine storage container and the urinal while blocking a fluid connection between the first urine storage container and the urinal, wherein the switching system includes a plurality of switches configured to provide the command signal, switch being arranged in each of the first and second urine storage containers, each switch including first and second contact elements biased apart from one another in a first condition corresponding to a first volume, and electrically engaging one another in a second condition corresponding to the second volume. 2. The system according to claim 1, wherein each of the first and second urine storage containers includes a cavity having a bag, the bag movable within the cavity between the first and second volumes. 3. The system according to claim 2, wherein the bag includes a quick disconnect removably coupled to the distribution system. 4. The system according to claim 3, comprising an additional storage container and a new bag, the additional storage container configured to receive a full bag from one of the first and second urine storage containers, and the new bag configured to replace the full bag and connect to the distribution system at another quick disconnect on the new bag. 5. The system according to claim 1, comprising a light electrically connected to each switch, the light configured to illuminate during a full bag condition. 6. The system according to claim 1, wherein the flow diverter valve automatically switches between the first and second urine storage bags in response to the command signal. 7. A waste handling system comprising: a urinal having a urinal outlet;first and second urine storage containers; anda distribution system fluidly interconnecting the urinal to the first and second urine storage containers, the distribution system includes a switching system selectively fluidly connecting the urinal outlet to at least one of the first and second urinal storage containers in response to an input, wherein at least one of the first and second urine storage containers include a cavity having a bag, the bag movable within the cavity between first and second volumes, and comprising an electrical switch that communicates with the bag, the electrical switch including first and second contact elements biased apart from one another in a first condition corresponding to the first volume and electrically engaging one another in a second condition corresponding to a second volume. 8. The system according to claim 7, comprising a light electrically connected to the switch, the light configured to illuminate during a full bag condition. 9. The system according to claim 7, wherein a flow diverter valve is in communication with the switch, and the switch provides a command signal to the flow diverter valve, the flow diverter valve is configured in response to the command signal to change between first and second positions corresponding respectively to a fluid connection between the first and second urine storage containers blocking flow to one of the first and second urine storage containers while enable flow to the other of the first and second urine storage containers. 10. A waste handling system comprising: a urinal having a urinal outlet;first and second urine storage containers; anda distribution system fluidly interconnecting the urinal to the first and second urine storage containers, the distribution system includes a switching system selectively fluidly connecting the urinal outlet to at least one of the first and second urinal storage containers in response to an input, further comprising a waste processing unit including a urinal inlet configured to receive urine, and a pumping element fluidly connected between the urinal inlet and the urinal outlet, and a differential pressure valve selectively fluidly connecting the urinal outlet to at least one of the first and second urine storage containers, the differential pressure valve includes first, second and third pressure inputs, the first pressure input corresponding to a pressure from the urinal outlet, the second pressure input corresponding to a pressure from the at least one of the first and second urine storage containers, and the third pressure input corresponding to a reference pressure, the differential pressure valve configured to open and close in response to a differential pressure between the first and third pressures, wherein the differential pressure valve is configured to automatically open at a selected pressure differential. 11. The system according to claim 10, wherein at least one of the first and second urine storage containers include a cavity having a bag, the bag movable within the cavity between first and second volumes, and comprising a mechanical device configured to be actuated in response to the bag changing from the first volume to the second volume, the mechanical device providing a visual indicator of the bag being full at the second volume. 12. The system according to claim 11, comprising a manual flow diverter valve configured to be manually changed between first and second positions corresponding respectively to a fluid connection between the at least one of the first and second urine storage containers and the other of the at least one of the first and second urine storage containers. 13. The system according to claim 10, wherein the reference pressure is generally constant and the second pressure increases as the at least one of the first and second urine storage containers transitions from an empty condition to a full condition. 14. The system according to claim 13, wherein the reference pressure corresponds to a cabin pressure. 15. The system according to claim 10, comprising a shut-off valve fluidly arranged between the urinal outlet and the differential pressure valve.
