Part of this is simply that air travel is inherently dangerous and, thus, standards are much higher. “If you fly commercial airlines, often they’ll 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 shudder to think that one of these things might come down on a crowded highway.” Part of the solution, Singh said, is comprehensive contingency planning: “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
