In today’s lesson, entitled Drone Worry, you will listen to a passage about why remote-controlled drones and airplanes have the U.S. Federal Aviation Administration worried. You will also learn about some of the practical ways in which drones are being used today. Listen carefully to the passage and then answer the questions that follow. It’s always a good idea to take notes as you listen, but remember: don’t let your note-taking distract you from your listening.

Lesson Forty PASSAGE ONLY track:

 

The Alpine skier Marcel Hirsch was midway through his run at the World Cup Slalom Race in Italy when a camera-carrying drone plunged from the sky and crashed into the slope, just centimeters behind him. Footage shows Hirsch, who appears to be oblivious to his near miss, carrying on down the hill towards the finish line.   Later, the rattled skier told the BBC, “This can never happen again. This can be a serious injury.” The incident prompted the International Ski Federation to immediately ban camera drones from all World Cup events. Drones, announced the federation, are “a bad thing for safety.”

The sporting world is not alone in its concern for drone safety. One 2015 report painted a disconcerting picture of how dangerous the skies can be when crisscrossed with both drones and manned aircraft. From December 2013 to September 2015, there were 327 “close encounters” in U.S. airspace in which drones put airplanes at risk. At least 241 of those incidents met the Federal Aviation Administration’s (FAA) definition of a “near-collision”—two aircraft flying within 500 feet of each other. And about a third of those involved commercial jets carrying numerous passengers.

These disturbing statistics have forced the FAA to come up with new measures to ensure air traffic safety.  Drone owners aged thirteen or over will now have to register their drones on the FAA website to make it easier for the administration to identify owners when a close encounter occurs. The FAA has also prohibited drones from flying higher than 400 feet and has stipulated that they cannot be flown within five miles of an airport. The requirements cover drones and remote-controlled airplanes that weigh more than half a pound. This means that most commercially sold “toy” drones would need to be registered, too.

life saving droneDespite these sterner rules and tighter restrictions, drone flying is attracting an ever-larger number of hobbyists and enthusiasts. And with drones becoming increasingly affordable—some costing as little as $30—children, too, can easily get their hands on them. In the United States, an estimated 1.6 million small, unmanned aircraft were sold in 2015 alone. Of that total, more than half were purchased in the three months leading up to Christmas.

The possibilities are endless. Already, drones are being deployed in emergency search-and-rescue operations, police surveillance, traffic control, TV and movie aerial photography, scientific and environmental research, and wildlife protection activities like spotting and capturing poachers. In the not-too-distant future, we can expect drones to deliver our mail, bring piping hot pizzas to our doorstep, and airlift us supplies during times of natural disaster. And like it or not, drones have a multitude of military uses as well.

While “drone spotting” is still something of a novelty, experts contend that it’s only a matter of time before drones become as commonplace as cars and mobile phones. This makes it all the more imperative that we raise drone safety awareness now, before the skies are swarming with them like a cloud of gnats.
