When Russ Van Der Werff heard about the Chinese surveillance balloon detected drifting over the US, potentially spying on sensitive installations, he was concerned, naturally. But as vice president for stratospheric solutions at Aerostar, a company that makes high-altitude balloons, he was also kind of psyched. For years Van Der Werff has been working to convince government and commercial customers that Aerostar’s products offer serious advantages as surveillance platforms. It isn’t always easy. “There’s always someone saying, ‘Oh, now the balloon kooks are here,’” he says. “Well, now it looks like other people think it’s a good idea, too.”

For all the furor caused by China’s ill-fated balloon, its turn in the spotlight has been something of a coming-out party for a technology that’s spent the past decade quietly polishing its abilities. “We don’t believe a stratospheric balloon is the be-all and end-all,” Van Der Werff says, “but there are times when it’s a better fit.”

Balloons have been used for military surveillance since 1794, when France deployed one during its war with Austria. Both sides used them during the American Civil War, and the US Navy used blimps to hunt Nazi submarines during World War II. But the development of airplanes and high-altitude spy planes made lighter-than-air craft seem quaint, and the US Navy retired its last airship in 1962.

In time new technology would bring balloons back around. Continue reading Businessweek: Spy Balloons Are the Slow and Silent Future of Surveillance

On February 13, 2023 I went on WNYC’s “The Brian Lehrer Show” to talk with Brian about my New York magazine article “Understanding the UFO War” and a few other things. It was my sixth time visiting the program.

On Sunday at 7.43 p.m. EST, as 100 million Americans were watching the Philadelphia Eagles pull ahead of the Kansas City Chiefs in the second quarter of Super Bowl LVII, Air Force general Glen VanHerck, head of U.S. North American Aerospace Defense Command and Northern Command, told reporters on a briefing call that he could not rule out the possibility that the object U.S. fighters had just shot down — the third in three days — had come from outer space. When asked “Have you ruled out aliens or extraterrestrials?,” VanHerck replied, “I’ll let the intel community and the counterintelligence community figure that out. I haven’t ruled out anything.”

To a public long habituated to the idea that the military has for decades hidden and lied about its knowledge of alien visitors, the statement sounded close to an outright acknowledgement that the big ET cover-up is real and finally coming undone. But as much as we want to believe “the truth is out there,” what’s actually going on behind the military’s new campaign against unidentified flying objects is something quite different, though mysterious and scary in its own way. Continue reading New York: Understanding the UFO War

Cape Air Flight 1965 from Boston to Provincetown is a quintessential puddle jumper. Several times a day, the seven-passenger Cessna 402 takes off from Boston Logan International and climbs to its maximum altitude of 800 feet. Twin propellers thrumming, it heads toward the sandy spiral tip of Cape Cod. Fourteen minutes later, the 402’s wheels screech onto the runway at Provincetown. Total distance traveled: 45 miles, versus the 120-mile road-and-bridge route, a slog that can stretch to six hours on Friday afternoons in August.

This isn’t cutting-edge aviation. Cape Air Corp.’s Cessnas are up to 40 years old and lack most comforts—including bathrooms—that even folks in steerage class demand. But Cape Air, focused entirely on short-range flights, aims to open a doorway to the future. As civil aviation works to become carbon-neutral worldwide by 2050, the first electric planes to replace fossil-fuel models will almost certainly ply short hops such as Boston-Provincetown.

Cape Air, which has about 100 aircraft flying 40 routes, all under 250 miles, is ready for the change. “If an electric airplane were built today, we would start implementing that,” says Senior Vice President Jim Goddard. The company is the first customer for the Alice, a nine-passenger, twin-engine plane being developed by Eviation Aircraft Ltd., a startup based just north of Seattle. Cape Air has signaled it’s ready to buy as many as 75 of the planes, which will have a range of 280 miles at a cruising speed of 185 mph. Eviation hopes to have the Alice in service by 2027.

Carbon-free aviation is starting with such modest goals because it’s far more difficult to electrify a plane than a car. Pound for pound, today’s best batteries store about one-sixth as much energy as jet fuel. Since flying machines must expend energy keeping every pound of their own weight aloft, an electric aircraft can’t go as far, as fast or as high.

The U.S. awoke Wednesday morning to a massive and as-yet unexplained disruption in the national air travel system triggered by the failure of an obscure but crucial FAA service called Notice to Air Missions, or NOTAM. The shutdown began at 3:30 a.m. and by 7 a.m. had resulted in the delay of over a thousand flights, as the FAA halted the departure of all domestic flights. Planes already in the air were allowed to fly as planned. By 9 a.m. the FAA had managed to restore the system and reported that normal air operations were “resuming gradually across the U.S.” but significant delays remained widespread.

The disruption came on the heels of a big holiday meltdown that caused Southwest Airlines to cancel more than 15,000 flights amid bad weather and a failure of its scheduling system, and will no doubt put further heat on Transportation Secretary Pete Buttigieg, who critics say has failed to use his regulatory powers to protect the integrity of the nation’s air travel system.

NOTAMs, originally called “notice to airmen” and still referred to as such in international aviation, is a system by which pilots are alerted to potential hazards or obstructions they might encounter en route, such as runway changes at the destination airport, problems with navigational beacons, or the closure of airspace surrounding a sports game or a presidential visit. Pilots receive NOTAMs as part of their standard pre-flight preparations, along with weather and other information which might affect the flight. They can also receive them en route from air traffic controllers or via automated weather information broadcasts. NOTAMS rarely concern matters of urgent safety, and it’s entirely possible that domestic air travel could operate safely without it for a day or two, but as a legal matter pilots cannot fly without them.

At 7 a.m. the FAA tweeted that it was working to reboot the system and that  “some functions are beginning to come online.” An hour later, it reportedthat departures had resumed at Newark and Atlanta airports and that departures would begin again elsewhere at 9 a.m. The resumption of NOTAM service did not mean an immediate return to normal flight operations, however, as dispatchers and air traffic controllers were left to untangle the backlog that had developed over the preceding hours. At 9:30 a.m. FlightAware listed 4,592 flights delayed within, into, or out of the United States and 825 flights canceled—though it was impossible to say how many were directly due to the NOTAM system failure.

It’s as yet unclear what might have caused the shutdown. At fault could be an inadequately maintained computer system of the kind that contributed to last month’s Southwest debacle or some kind of malicious attack. Wednesday morning President Biden told reporters “I just spoke with Buttigieg… they don’t know what the cause is.” White House press secretary Karine Jean-Pierre tweeted that “There is no evidence of a cyberattack at this point, but the President directed the DOT to conduct a full investigation into the causes.”

Elon Musk, who in November bragged that his free-speech absolutism was so pure that wouldn’t ban an account devoted to tweeting his plane’s in-flight location, reversed course with a vengeance earlier this week. He banned not only the @ElonJet account but all the accounts belonging to its creator, Florida college student Jack Sweeney. Then Thursday night he went still further, suspending more than a half-dozen prominent journalists who had been covering the controversy.

In his defense, Musk argued that tweeting information about his flights was equivalent to “doxxing,” a practice in which online harassers publish a victim’s address, phone number, or other personal information in order to encourage other people to harass them.

“Criticizing me all day long is totally fine, but doxxing my real-time location and endangering my family is not,” Musk tweeted Thursday night. (He said that a stalker had used the information to track his young child in a car, though he doesn’t have appeared to have filed a police report, and he hadn’t used his jet on the day in question.)

The controversy has put the spotlight on a previously little-discussed area of aircraft operations and raised the question: Why is aircraft location information made available freely and instantaneously?

It turns out there is actually a very good reason. Continue reading Slate: Is Elon Musk Right That Flight Tracking Is an Invasion of Privacy?

Air travel is about to get a hell of a lot faster — at least that’s what the headlines say. “American Airlines to buy supersonic jets amid clamor for ultra-fast travel,” declared the Washington Post on Wednesday morning. “World’s fastest airliner ‘Overture’ to usher in new era of supersonic travel,” the New York Post proclaimed. They were pegged to American Airlines’ announcement that it had placed orders for 20 supersonic Overture jets from a start-up called Boom. The planes will carry up to 80 passengers at Mach 1.7. Better yet, they’ll burn a special fuel that will make them carbon neutral.

It’s all very exciting, if it happens. But there are many reasons to believe it won’t — not least that, for years, similar claims have continuously come up empty. “It’s just PR,” says aviation analyst Brian Foley. Supersonic air transportation is, he says, “still a long way off,” adding, “It’s fun to dream.”

To hear Boom tell it, the project is moving along at a blistering pace, and later this year the company says it will break ground on a factory in North Carolina. “We’ll begin production in 2024, with the first Overtures coming off the line in 2025,” Boom president Kathy Savitt says. Flight testing and certification will follow in short order. “We estimate that the very first passengers will be able to fly an Overture by the end of 2029,” she says.

Boom has made similarly ambitious claims before. Back in 2016, the company said it would be making three-hour transatlantic flights by 2023. In the meantime, it hasn’t even flown a scale model. “It’s always a decade in the future,” says Foley. Continue reading New York: The Eternal Disappointment of the Return of Supersonic Travel

The U.S. aviation industry has been in a tizzy this week over fears that Wednesday’s launch of national 5G cellular service would create chaos by interfering with aircraft sensors. Ten major airlines wrote to the Biden administration predicting that the “nation’s commerce will grind to a halt.” Sure enough, come Wednesday, a number of airline flights were canceled, including all of Emirates’ U.S. flights. Generic Rapamune sirolimus delivered bu Emirates post, president Tim Clark called the 5G rollout “delinquent, utterly irresponsible.”

But by Thursday, the story had already fizzled. As commerce trundled along unfazed, several airlines un-canceled their flights and the Federal Aviation Administration (FAA) announced that at least 78 percent of the U.S. commercial fleet would be unaffected in any way by the 5G rollout. Some observers went so far as to label the issue “incredibly dumb.” The main remaining question was why it had even turned into a thing in the first place.
