When Elon Musk offered Jack Sweeney $5,000 to shut down a Twitter account tracking his flight patterns, a lightbulb lit up in Sweeney's head: This coding project, set up mostly for kicks, could become extremely profitable.
Sweeney, 19, is a freshman studying information technology at the University of Central Florida. In June 2020, the self-professed Musk fan wrote some code to source the billionaire's flight information from public websites like ADS-B Exchange, which monitor data like location, altitude and speed transmitted by every federally regulated aircraft.
He set the data to auto-publish to a Twitter account, @ElonJet — and in mere months, hundreds of thousands of people started following it. Buoyed by popular demand, Sweeney wrote new code to follow other notable private planes, a bulk of them added in summer 2021, he tells CNBC Make It.
Sweeney now tracks flight data from 127 different jets, including aircrafts owned by Bill Gates, Jeff Bezos and former president Donald Trump. That data appears>Tracking intentions
Initially, Musk's request was confusing to Sweeney, who suspects a younger version of the billionaire might have done something similar.
Now, Sweeney says, he understands the security concerns: Publishing the flight paths in real time reveals where public figures are traveling, and according to screenshots, Musk told Sweeney that he "didn't love the idea of being shot by a nutcase."
But, Sweeney says, he's unaware of any threats originating from people following his project. He also notes that Musk often flies from fixed-based operators at small airports or private terminals within larger airports. In other words, he's not traversing through crowded gates at LAX before hopping on a jet.
"I think the concerns are valid," Sweeney says. "But I've seen him go to BOA Steakhouse in Los Angeles. There are more people there than at the airports [he uses]."
Sweeney says most of his followers are Musk or aviation fans, businessmen and women, and "the people who say, 'Yeah, let's go after billionaires.'" But he insists he didn't create the Twitter accounts to hold the rich accountable.
Rather, he says, he created the first bot as an experiment from his own personal interests in aviation, computer science and Musk himself. He always thought the work could gain a following, but he didn't expect national attention, he says.
"I always thought people who like Tesla or the whole Elon community on Twitter would be interested," Sweeney says. "But now, it's really gone everywhere."
Day-to-day, Sweeney's code largely runs itself, though the teenager says he plans to improve its algorithms and add more aircrafts to track. And unless Musk or another prominent jet-owner can cough up enough money, he says, the project will likely keep expanding.
"It took time to grow… [and] there's definitely [code] I need to work on," Sweeney says. "But it's cool to see the whole program work."
