Huber said about Amazon: “They say that many packages are light – a drone can carry a kilogram for 15 minutes. If you have a vehicle that can go into a neighborhood, it can deliver from that vehicle. You need a 15-minute distance, and typical drones have about that distance.” It’s one way, he said, to make sure people are safe. “The larger the distance, the more dangerous it becomes.” Of course, safety is still a big worry – Singh points out that for a passenger airplane to be allowed to fly, it can only have one serious failure every one million hours. Drones, he said, are much less safe. “The Reaper drone, for example, has one failure in 10,000 hours,” Singh said.
What determines if a passenger plane is allowed to operate?
The number of serious failures every one million hours The number of minor failures every one million hours The number of serious failures every 10,000 hours The number of times it has been inspected within one week prior to take off
