"So if you forget to put your phone on airplane mode, no, it's not the end of the world. The plane will not fall out of the sky, and it won't even mess with the systems onboard. However, it does have the potential to mess with the headsets."

The pilot explained that no matter how many passengers are on board a plane, if a phone tries to connect to a radio tower, the radio waves can interfere with the radio waves of the pilots' headsets.

He explained that it creates a buzzing noise in the headset, which makes communication difficult.

He said: "It kind of sounds like there's a mosquito in my ear. Like I said, it's not [the] end of the world, but it's definitely pretty annoying when you're trying to copy down instructions, and it sounds like there's just, like, a wasp or something flying around you."
