Travel the World in an App


In early 2020, Christine Dibble had recently retired from the federal government and was desperate to travel more, however the coronavirus outbreak put those plans on hold.

Grounded at home in Washington Grove, Md., Dibble began to mess around with a flight-tracking app, and it opened the skies for her.

Flightradar24 is certainly one of several sites that compile public details about aircraft locations, flight paths, ownership records, altitude and more for display in an interactive map. People can see details about planes and where they’re heading almost anywhere on this planet, including Antarctica.

Dibble, a former technology employee for the Environmental Protection Agency, had little knowledge about aviation, however the app satisfied her wanderlust and sparked curiosity about what was happening round her.

“The surprising thing about Flightradar to me is that it triggers my imagination,” Dibble told me. “What are people up there on that plane doing? Are they on vacation? On business?”

Peering at aircraft icons within the app, Dibble feels excited for tourists she imagines on the flight departing a close-by airport for Lisbon. She empathizes with parents when she sees the virtual image of an emergency helicopter on its option to a neighborhood children’s hospital.

“There are all these stories here,” she said.

Not way back, the app showed that a small plane flying low near her home had taken off near a Central Intelligence Agency training base. Dibble, her husband and daughter dreamed up scenarios of a Russian oligarch being whisked away in handcuffs.

Flight-tracking sites are one other example of a technology that makes obscure information accessible and relevant for us mere mortals and helps connect us to others. It’s pretty amazing that we will Google whatever we’re interested in or video chat with friends distant. Following flights on the opposite side of the world is one other marvel.

Flightradar24 began within the 2000s to market a Swedish ticket booking website, its director of communications, Ian Petchenik, told me. Harnessing a technology called Automatic Dependent Surveillance-Broadcast, the corporate’s founders and employees began installing ADS-B receivers on rooftops in Sweden to choose up radio signals of planes transmitting their locations to other aircraft and air traffic controllers.

The interactive map of air traffic proved more popular than the booking service. The flight-tracking service was born, said Petchenik.

Now there are about 34,000 Flightradar24 receivers that individuals world wide have agreed to placed on their homes and industrial buildings and in other spots. Flightradar24 combines those signals with other information, including a database of aircraft owners and industrial airplane flight schedules, to assemble the information in a digital map.

You may be wondering: Is that this a security risk? Representatives for the Federal Aviation Administration told me that the agency limited the available data on aircraft related to the Defense Department, Department of Homeland Security and the Justice Department. Air Force One doesn’t appear in Flightradar24, for instance. Owners of civilian planes can request limits on their travel data disclosures, too.

Petchenik believes it’s vital for real-time details about activity in shared airspace to remain public.

Flightradar24 told me that usage of the tracking service spiked because the pandemic kept many would-be travelers like Dibble at home. And last week, some people couldn’t access Flightradar24 because so many users were following House Speaker Nancy Pelosi’s circuitous flight path to Taiwan, taken to navigate around potential conflicts with Chinese military planes.

There are other flight-tracking sites including FlightAware and ADS-B Exchange. But Jerry Dyer and Gilly Prestwood, who run Big Jet TV, a YouTube aviation specialty channel, said that Flightradar24 is the app of alternative for each casual looky-loos and aviation buffs.

Some people use the app to estimate arrival times of family and friends, and anxious fliers use it to feel safer about plane travel, they said. News organizations have used flight-tracking services to hunt for clues from corporate executives’ travels. Dyer, Prestwood and Mindaugas Kavaliauskas, a photographer who published a book of images related to travel, said aviation hobbyists use apps to trace famous or rare planes, gawk at 3-D satellite images from cockpits and debate the merits of 1 style of jet versus one other.

After On Tech asked readers about technologies that stoked their creativity, Dibble emailed us about her affection for Flightradar24. I didn’t get the appeal at first, but I downloaded the app and my mind began to fireplace, too.

Now I imagine fancy people or tourists on helicopter flights hugging the virtual Manhattan skyline. Last week, I clicked on the icon of an airplane the app showed was miles above my neighborhood and saw that it was headed to Paris. Sigh. Lucky them.

Dibble knows that an app is not any substitute for traveling in real life. She’ll soon be certainly one of those people on a flight sure to Lisbon that she’s been eyeing in Flightradar24. But she still looks on the app several times a day.

“It’s a way of connection to the larger world,” she said.
