Firefighting is seen as its main role, with a 530-gallon liquid tank about the same size as many other manned aircraft used to put out forest fires. The large tank also makes the FLYOX ideal for aerial application of crops, making Kansas a perfect place to test the drone. And because the tank can also carry fuel, the FLYOX could stay aloft for 50 hours at a time for SAR ops that would be impossible with a human crew.
