New NTSB Report Reveals What Probably Occurred to United Flight 1093 Over Utah
United Flight 1093 was cruising excessive above Utah’s Colorado Plateau area, close to Moab, when the morning calm was shattered by a shock and violent affect.
At 0643 MDT on 16 October 2025, the Boeing 737 MAX 8 (reg. N17327) was cruising at 36,000 ft on a scheduled flight between Denver Worldwide Airport (DEN) and Los Angeles Worldwide Airport (LAX) when the captain noticed one thing out on the horizon. It was distant. It was small. And earlier than he might level it out, the article struck the primary officer’s (FO) ahead windshield with a pointy bang that echoed by way of the flight deck.
Each pilots have been blasted with fragments of glass. The captain acquired “a number of superficial lacerations” on his proper arm. The FO was unhurt. All 111 passengers have been secure.
What hit them instantly sparked intense media hypothesis. It turned instantaneous fodder for armchair aviation consultants on social media inside hours of the accident.
Now the NTSB’s preliminary report offers us the clearest image but of what performed out contained in the cockpit and what was drifting by way of the sky that morning. And new data from WindBorne Methods, the operator of the balloon that was within the space on the precise second of the strike, reveals how the corporate is already altering its operations.
A Calm Cruise Turns Chaotic
United Flight 1093 had simply crossed into Utah airspace when the article hit the FO’s windshield. The outboard layer was destroyed. Glass sprayed throughout the cockpit. The crew saved their composure.
The captain handed flying duties to the FO and moved into guidelines mode. Cabin pressurization held regular all through the occasion. The crew contacted dispatch, notified the flight attendants, and started getting ready to divert the plane to essentially the most appropriate diversion airport. On this case, it was Salt Lake Metropolis Worldwide Airport (SLC), about half-hour and 160 nautical miles to the northwest of 1093’s location.
Then one other complication. The FO’s window overheat mild illuminated. The crew labored the suitable guidelines and continued the descent towards SLC with out additional incident.
The captain cleaned and bandaged his personal wounds, briefed the cabin, after which took again the controls for the strategy and touchdown.
Regardless of every thing that had simply occurred, the touchdown on SLC’s Runway 16L was textbook. The MAX rolled to the gate underneath its personal energy with fireplace crews in escort. Paramedics handled the captain on arrival. Nobody else on board was damage.
However the thriller was simply starting.
One thing Was Up There
As soon as on the bottom, investigators started matching the time and site of the strike with any objects that may have been within the space. Plane. Climate balloons. Even reentry particles.
One lead stood out nearly instantly.
A WindBorne Methods international sounding balloon (GSB) had been drifting throughout the area that morning. It had been launched from Spokane, Washington, at 1129 MDT the morning earlier than and had floated from Washington by way of Oregon and Nevada. By the point United 1093 approached Moab, the balloon had modified path and was crossing Utah.
Most significantly, it stopped speaking with the bottom throughout the similar seven-minute window because the affect.
Its final reported altitude was 35,936 ft. United 1093 was at 36,002 ft. They have been on almost reciprocal tracks. That balloon’s final coordinates positioned it lower than one diploma from the estimated strike location.
WindBorne says the balloon was working legally underneath Half 101 as an unmanned free balloon. Their platforms are constructed with skinny plastic movie, a light-weight avionics package deal, and small silica ballast that’s designed to interrupt up with out inflicting hurt. No giant steel construction. No inflexible elements.
Even so, the timing is difficult to disregard.
The NTSB has not recognized the article. However the report makes the proximity and altitude match virtually simple.
And, in Windborne’s protection, its CEO, John Dean, publicly speculated that the collision might have been the fault of one in all its GSBs. The corporate has been clear and cooperative all through your entire investigation.
A Laborious Hit for a Powerful Windshield
United’s 737 was fitted with a PPG Aerospace windshield manufactured in March 2023. Like all fashionable transport class windscreens, it was constructed to deal with a four-pound hen strike with out penetration and to take care of cabin stress even when one pane fails.
The 737’s windshield makes use of a number of layers.
From the surface in, the construction consists of:
A thermally tempered glass outer paneA conductive heating filmA urethane interlayerA vinyl fail-safe interlayerAnother structural tempered glass paneAnd a chrome steel Z-bar body encased in a moisture seal to connect it to the fuselage
On 1093, the outer pane was destroyed. A number of layers behind it have been broken. Rivets alongside the body have been sheared. The internal structural glass held precisely because it was designed to, which is why the cabin stayed pressurized and the airplane remained flyable.
Had the article absolutely penetrated the windshield, the end result might have been very completely different.
The NTSB eliminated your entire meeting and despatched it to Washington for forensic evaluation. In addition they pulled the flight information and cockpit voice recorders, which confirmed the flight’s heading, altitude, and pace in the meanwhile of affect. The MAX was monitoring southwest at 233 levels at a groundspeed of 395 knots.
WindBorne Responds With New Security Measures
Shortly after the NTSB launched its preliminary report, WindBorne supplied up to date data on the steps it has already taken. The corporate confirmed that it has cooperated absolutely with investigators and can proceed to take action.
WindBorne stated its flight programs are constructed to stop midair impacts and to scale back danger within the uncommon occasion one thing goes flawed. The corporate additionally expressed aid that United Flight 1093 landed safely with solely a single minor damage and restricted plane harm.
WindBorne has already applied 4 new security enhancements throughout its operations.
Decreased Publicity in Business Airspace: WindBorne balloons will now not keep superpressure impartial buoyancy inside the first industrial altitude bands between FL300 and FL400. This modification cuts balloon publicity inside that altitude vary by roughly 50 p.c fleetwide.
Enhanced Air Site visitors Coordination: Along with the reside dashboard accessible to air visitors organizations, WindBorne now supplies automated electronic mail reviews each two hours for balloons working inside a given airspace. Alerts are additionally generated when a balloon enters or exits that area.
Lively Collision Avoidance Growth: WindBorne has built-in reside international ADS-B information to establish potential conflicts. The detection system is lively now, and automatic avoidance algorithms are at the moment being examined and are anticipated to be deployed quickly.
Payload Geometry and Mass Optimization: The corporate is refining its payload design to additional cut back cross-sectional density and affect power. This consists of evaluating lower-density ballast supplies and decreasing total payload mass.
WindBorne says it has all the time aimed to exceed Half 101 security requirements for top altitude balloon programs. The UA1093 incident strengthened the necessity for steady enchancment, and the corporate says these modifications have been applied instantly to strengthen safeguards.
The Investigation is Ongoing
The NTSB assigned specialists in supplies engineering, plane efficiency, meteorology, operations, air visitors management, and each recorders. The FAA, Boeing, United, and WindBorne are collaborating events.
One element value noting: The NTSB didn’t journey to the scene. This can be a Class 3 investigation, which is typical for an occasion involving substantial harm, an damage, and an unresolved midair collision that didn’t end in lack of the plane.
The investigation is ongoing. The ultimate report will decide what truly struck United Flight 1093 and whether or not any procedural or regulatory modifications are advisable.
As for the plane concerned within the incident, N17327, it was ferried to Chicago Rockford Worldwide Airport (RFD) on 19 October 2025, the place it has been present process repairs since.
WHAT WE KNOW SO FAR:
Right here is the clearest image the preliminary report offers us:
United Flight 1093 collided with one thing at 36,000 feetThe cockpit was showered with glassOnly the captain was injuredThe airplane remained pressurizedThe crew diverted safely to Salt Lake Metropolis Worldwide AirportA high-altitude climate balloon was in the identical place on the similar momentThat balloon misplaced contact in the course of the precise timeframe of the strikeNo different plane or reentry objects matched the locationThe plane concerned within the collision, N17327, stays out of service
Nothing is confirmed but. However the items are lining up.
No matter hit United Flight 1093 did actual harm. The images of the shattered windshield make that clear. However the internal pane held. The crew dealt with the emergency with textbook self-discipline. The airplane did what it was engineered to do.
Most significantly, each single individual on board United Flight 1093 walked away from it.
Now, the NTSB will proceed inspecting the proof from the window, the recorders, and the flight paths of each the MAX and the balloon.
Whether it is confirmed to be a climate balloon, which the early clues strongly point out, the true focus turns into understanding the way it occurred and what wants to vary so it by no means occurs once more.
