The thriller of what struck United Flight 1093 over Utah final week could also be one step nearer to being solved.
The incident occurred on Thursday, 16 October, when a United Airways Boeing 737 MAX 8, working from Denver Worldwide Airport (DEN) to Los Angeles Worldwide Airport (LAX), was cruising at 36,000 ft over southern Utah. Roughly 37 minutes into the flight, one thing slammed into the plane’s proper windshield, shattering the outer pane and injuring the captain. Regardless of the affect, the plane remained pressurized.
The crew instantly descended to 26,000 ft and diverted to Salt Lake Metropolis Worldwide Airport (SLC), the place the plane landed safely roughly 50 minutes after affect.
The Nationwide Transportation Security Board (NTSB) is main the investigation, and the broken windshield has been despatched to its laboratory for evaluation.
From House Junk to Spy Balloons and Aliens. Now, a Potential Reply.
Since information of the United Flight 1093 incident was made public, hypothesis has run rampant throughout the web, with theories starting from micrometeorites and SpaceX satellites to Chinese language spy balloons — and sure, even aliens.
However late Monday night, a doable clarification surfaced on social media.
John Dean, cofounder and CEO of WindBorne Techniques, a Palo Alto, Calif.–primarily based aerospace firm that designs and operates long-duration climate balloons, introduced on X that certainly one of his firm’s balloons could have been concerned within the collision.
“I believe this was a WindBorne balloon,” Dean wrote. “We realized about UA1093 and the potential that it was associated to certainly one of our balloons at 11pm PT on Sunday and instantly regarded into it. At 6am PT, we despatched our preliminary investigation to each NTSB and FAA, and are working with each of them to analyze additional.”
WindBorne’s Preliminary Findings
Dean confirmed that WindBorne operates “a constellation of long-duration light-weight climate balloons to enhance climate forecasts, with a lot of our knowledge going to each US and worldwide governments.”
He emphasised that the corporate complies with FAA Half 101 rules and worldwide requirements. “We file NOTAMs, comply with all specs required by FAA 14 CFR Half 101, and share all reside balloon positions with the FAA by way of API and our web site,” he stated.
The corporate’s present operational balloon design is “about 2x lighter” than earlier variations, weighing roughly 2.4 kilos (1 kilogram) at launch and getting lighter throughout flight.
In keeping with Dean, the system “is designed to not pose a danger to human life within the worst-case occasion of a collision. That is what the FAA 101 and ICAO weight limits are for. And certainly, there have been no critical accidents and no depressurization occasion to my data because of the collision.”
I discover this extraordinarily regarding and unacceptable within the case of a collision, no matter what the official rules are. It resulted in damage to a pilot, which I’m merely not okay with in any respect.

Nonetheless, Dean admitted to being “extraordinarily involved” by the injury to the United plane. “I’m nonetheless stunned to see spallation of the windshield on the within. I discover this extraordinarily regarding and unacceptable within the case of a collision, no matter what the official rules are. It resulted in damage to a pilot, which I’m merely not okay with in any respect.”
Technical Response and Fast Modifications
WindBorne has reportedly taken rapid steps in response to the occasion.
“As talked about, we’re working carefully with the FAA on this,” Dean continued. “We haven’t but acquired any operational steerage. Regardless, we simply deployed a software program change to attenuate time at lively flight ranges and are manually checking it throughout the total constellation. Moreover, we’re actively engaged on new {hardware} designs to cut back affect power magnitude and focus.”
Dean defined that light-weight balloons can’t carry ADS-B transponders due to strict energy and weight limitations. “Light-weight balloons can’t carry ADS-B — it’s not inside the energy funds, and the mixed transponder + energy system mass alone would put the balloon in a weight class that’s rather more harmful within the occasion of collision.”
He added, “We’ve been working with the FAA for some time now about what the fitting system for light-weight balloon reporting is. It’s a difficult downside and laborious to search out and implement a superb resolution between trade and regulators. I hope this incident accelerates us collectively discovering the fitting resolution.”
WindBorne balloons use GPS to find out their place, transmitting knowledge each 5–10 minutes by way of Iridium satellites. “We then share location and predicted flight paths with the FAA and different airspace authorities by way of each a web site and an API,” Dean stated.
A Assertion on the Firm’s Web site
Dean additionally revealed an announcement on WindBorne’s web site on Monday, reiterating the corporate’s perception that certainly one of its balloons was the thing that struck United Flight 1093:
“On Thursday, 16 October, International Object Particles (FOD) struck the windshield of UA1093, a 737 MAX plane, at roughly 36,000 ft. WindBorne started investigating this incident on Sunday, 19 October, and we consider that the FOD was possible a WindBorne balloon. At 6am PT Monday morning, we despatched our preliminary investigation to each the Nationwide Transportation Security Board (NTSB) and the Federal Aviation Administration (FAA), and are working with each organizations to additional examine this incident. We’re grateful that to our data there have been no critical accidents and no lack of pressurization. The flight, which was en route from Denver to Los Angeles, diverted to Salt Lake Metropolis. The airplane itself later flew to Chicago.”
He famous that WindBorne has carried out greater than 4,000 launches, including: “We’ve been coordinating with the FAA for your entire historical past of the corporate and file NOTAMs for each balloon we launch. The system is designed to be secure within the occasion of a midair collision.”
Dean stated the corporate instantly applied adjustments to “decrease time spent between 30,000 and 40,000 ft” and is “additional accelerating our plans to make use of reside flight knowledge to autonomously keep away from planes, even when the planes are at a non-standard altitude.”
The Information Level
In keeping with impartial analysts, there was a WindBorne balloon working in roughly the identical space and altitude as United Flight 1093 on the time of the incident. That balloon’s final transmission stopped reporting at 12:36Z, at coordinates 38.5314, -109.416, and an altitude of 10,953 meters, or simply below 36,000 ft.
Whereas the NTSB has not but verified this knowledge, it seems to align carefully with the timeline and site of the occasion.
If True, We Have Questions
On the time of writing, the NTSB and FAA haven’t confirmed the balloon concept or launched any official findings. The windshield from United Flight 1093 stays below evaluation on the NTSB’s supplies lab.
If the preliminary concept proves appropriate, it raises a number of crucial security questions.
What if the balloon or its ballast had penetrated the cockpit glass completely? What if particles had been ingested by the engines or change into entangled on the wing, altering the plane’s aerodynamics? These are the situations that investigators will possible research carefully within the coming weeks.
Nonetheless, one factor is obvious: this might have ended far worse.
And whereas a lot of the web continues to take a position, WindBorne’s transparency has been refreshing. Dean’s fast acknowledgment, technical element, and proactive security steps stand in sharp distinction to the secrecy typically related to aviation incidents.
From our vantage level, it seems that WindBorne adopted process and is publicly accepting the results head-on. We commend Dean’s transparency.
Avgeekery will proceed to comply with this story and convey you updates on United Flight 1093 as they change into obtainable.
