No one doubts that the pilots are seeing something, but psychologists and specialists in aviation medicine say there are plenty of reasonable explanations for such sightings other than extraterrestrial beings. Earthly sources of light reflected by clouds or haze, for example, or optical illusions wrought by fatigue after staring through a cockpit window for hours on end.
Another possibility is that the pilots were seeing some sort of experimental drone or other advanced technology about which they had not been briefed. Or, the objects were simply satellites, such as those launched in May by the Elon Musk-founded company SpaceX, which
prompted a flurry of UFO reports from puzzled observers, the news agency AFP reported.
