The reasoning: the C-Band 5G tech that the telecom industry is eager to push out to airports could interfere with various airplane instruments including radio altimeters, equipment that tells the airplane how high it's flying in low-visibility conditions. "This means that on a day like yesterday, more than 1,100 flights and 100,000 passengers would be subjected to cancellations, diversions or delays," reads a public letter, sent to the White House and signed by a number of US airline CEOs as well as UPS and FedEx. "To be blunt, the nation’s commerce will grind to a halt," they warned. ## C-Band Leader The White House recently reached an agreement with AT&T and Verizon to roll out the technology at a select number of airports as part of a test. It was a highly contentious issue that had more than just airline execs worried. Less than a day after the letter went out, the two carriers announced that they'll delay the rollout over to the concerns, [*The New York Times* is now reporting](). That's on top of delays that had already pushed the rollout from December to early this month. "To be very clear, we’re incredibly disappointed that we are at this point, that the entire US airline industry is facing major disruption as new wireless technology is activated," American Airlines CEO David Seymour wrote in a letter to staff, as obtained by the *Times*. "The two should be able to coexist, but that only comes with better understanding of potential impacts." Telecom industry players have downplayed concerns, arguing the technology was already being safely used in parts of Europe. But opponents were quick to point out that 5G networks were implemented differently there. **READ MORE:** [AT&T and Verizon will change their 5G plans after airlines warn of flight chaos.]() \[*The New York Times*\] **More on 5G:** *[Experts: Stop Wearing Radioactive “Anti-5G” Necklaces, Idiots]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
