| There's a world of difference. 1. There is evidence that drones exist. 2. The reports are being made by qualified recognised professionals, who are, at the time of reporting, clearly in good health, good state of mind, and sober (or they would not be in command of an aircraft). 3. The reports are sometimes made in real-time (pilots reporting to ATC over radio whilst on approach), or very shortly after the incident. 4. The reports are detailed (in some cases even describing the colour of the drone). 5. The incidents are backed up by secondary reports: e.g. drones being reported around an airport without necessarily causing an airprox incident. All that said, perhaps better data would help document the degree of risk. The drones that are directly radio-controlled (rather than having a programmed flight-plan) will usually operate on a small set of standard frequencies, which could be monitored and recorded. Add some video surveillance, and this could add more documentary evidence to the reports. |
