Part of the reason for this is that air travel is dangerous so standards are much higher. “If you fly commercial airlines, they often say, ‘Oh, a small component has failed – we have to go back to the gate,’” Singh said. “And that’s an established industry with 60 years of legacy! 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 vehicle has to do something reasonable.”
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
