Look up in the sky! What’s that? It’s the pizza you ordered. A drone is bringing it to you.
This could be the future. Drones are small machines. They use a propeller to fly and can track people and buildings using map coordinates. Many companies may soon use them to deliver packages. But is it safe to use drones? Some people think they could get in the way of air traffic. Other people do not like the idea of being tracked by a machine.
Gary and Jessica are talking about drone deliveries. Listen and find out what they think in this English lesson.

Gary: Did you know that very soon, you will be able to place an order on Amazon.com, and a number of other websites, and have your package delivered to you by a drone?
Jessica: Are you kidding?
Gary: I am not kidding.
Jessica: Wow! See, that is a game changer. That would be incredible.
Gary: It’s so exciting to think of the fact that we’re going to have these propeller-based devices just flying around in the air. But it’s going to have something we have to think about, and that’s air traffic control.
Jessica: Oh.
Gary: So, with all of that air traffic of all these drones, who’s going to maintain how many can be in the air?
Jessica: Are they operated by remote control? I mean, how do they hover?
Gary: I think they’re actually programmed with the coordinates of where you live, so it will use your phone’s GPS to actually track you. So, if you move, the drone will follow you.
Jessica: See, this is very fascinating. It’s a little scary…
Gary: It is.
Jessica: But it’s very cool. I think there’s potential for something really neat here.

Discussion
Gary tells Jessica that, soon, many companies will use drones to deliver packages. Jessica doesn’t understand how drones work. She doesn’t know how they hover or how they find people. Gary explains that drones use coordinates from people’s phones to find them. They fly by using propellers.
However, Gary thinks that there could be a problem with using drones. They might get in the way of airplanes. There might be too many of them in the air sometimes. Jessica agrees that drones are a little scary, but she thinks they have potential to be very useful in the future.
Do you think drones are scary or useful? Would you order something that was delivered by a drone?
