It might be difficult for the pilot to explain at an NTSB hearing why he was flying below 500’ AGL, but he could argue that he was far enough from
any persons, structures, vessels, vehicles.
Of course, if the engine fails, he would also have to explain his emergency landing without undue hazard to persons or property.
Bottom line: planes CAN fly lower than 500’ AGL, legally or not, and become a threat to UAS pilot.
We are the lowest on the Totem pole, and therefore give priority to all.
