Part of the reason for this is simply that air travel is dangerous so standards are much higher. “If you fly a passenger airplane, often they will say, ‘Oh, a small part isn’t working; we have to go back,’” Singh said. “And people have been flying passenger airplanes for 60 years! I hate to think that a drone might come down on a busy road.” Part of the solution, Singh said, is planning for every situation: “If things fail, the drone has to do something sensible.”
According to Singh, why do passenger airplanes often return to the gate?
A small part has failed A passenger identified a problem with the airplane They are in danger of coming down on a busy road Poor weather conditions
