“Engines, Errors, and Airspace: July’s Most Alarming Aviation Incidents Explained”
🛑 1. Alaska Airlines IT Outage Grounds Entire Fleet (July 20, 2025)
On the evening of July 20, Alaska Airlines and its regional affiliate, Horizon Air, initiated a system-wide ground stop across the United States due to a major IT failure. The disruption began around 8:00 p.m. Pacific Time, affecting check-in, gate assignments, crew scheduling systems, and departure management tools.
Key Details:
The ground stop lasted approximately three hours, during which hundreds of flights were either delayed or canceled, stranding thousands of passengers across major airports such as Seattle-Tacoma (SEA), Portland (PDX), and Los Angeles (LAX).
Although systems were gradually restored later in the evening, the ripple effect continued into July 21, with operational backlogs and rebookings.
Alaska Airlines has not confirmed whether the incident was caused by a cyberattack, but it notably follows a string of global aviation IT breaches, raising questions about cybersecurity preparedness.
Background:
This marks the second major outage for Alaska Airlines within a 12-month span. In late 2024, a similar incident affected their dispatch and communication systems, prompting regulatory concern from the FAA.
Industry Implications:
The outage exposes the high dependency of modern airline operations on centralized digital infrastructure, where even a partial disruption can cascade into system-wide shutdowns.
Experts stress the importance of cyber-resilience protocols, disaster recovery systems, and redundant IT frameworks to ensure continuity.
In light of increasing cyber threats targeting aviation, federal agencies are likely to tighten compliance norms and demand incident disclosure transparency from airlines going forward.
⚠️ 2. Delta Connection Avoids Mid-Air Collision with U.S. B-52 Bomber (July 18, 2025)
Delta Connection flight 3788, operated by SkyWest using an Embraer E175, narrowly avoided a catastrophic mid-air collision while approaching Minot International Airport in North Dakota. The incident occurred when a U.S. Air Force B‑52 bomber entered the civilian aircraft's airspace during final descent.
Key Details:
The pilot of Flight 3788 spotted the bomber visually and took immediate evasive action, executing a steep climb and go-around maneuver without prior instruction from Air Traffic Control (ATC).
The approach was cleared by civilian ATC; however, the military aircraft reportedly entered the airspace without timely communication or separation guarantees.
The pilot’s voice was later recorded reassuring passengers via an inflight announcement and post-flight video, acknowledging the "aggressive maneuver" and praising the crew's training.
Ongoing Investigation:
The Federal Aviation Administration (FAA) and the United States Air Force (USAF) have launched a joint investigation into the airspace breach.
Particular focus is being placed on the lack of coordination between civilian and military controllers, and whether existing radar systems failed to flag the proximity of the two aircraft in time.
Significance:
This close-call incident brings renewed attention to the fragility of shared airspace protocols in regions with both commercial and military operations.
Aviation analysts are calling for upgraded airspace deconfliction systems, enhanced radar integration, and cross-agency simulation drills to prevent recurrence.
The event has also sparked debate over transponder compliance and situational awareness training, particularly when military flights operate in proximity to public air routes.
🔥 3. Delta 767 Engine Fire After Takeoff from LAX (July 20, 2025)
On the same day as the Alaska Airlines outage, a Delta Air Lines Boeing 767-400, operating a scheduled international flight out of Los Angeles International Airport (LAX), experienced an engine fire shortly after takeoff.
Key Details:
Flames were visibly emanating from the aircraft’s right engine (GE CF6) and were captured on video by passengers and witnesses on the ground.
The flight crew declared an emergency, requested immediate return clearance, and landed safely without incident.
No injuries were reported, and emergency response teams at LAX were on standby upon landing.
Cause and Response:
Initial investigations suggest a compressor stall or turbine failure may have been the cause. Maintenance records of the aircraft, including recent engine servicing, are under review.
The aircraft was towed for technical inspection, and passengers were re-accommodated on another flight.
Takeaway:
While engine fires are rare occurrences, commercial pilots are trained extensively to handle such emergencies, and aircraft systems are designed with fire suppression protocols that activate automatically or manually.
This event demonstrates the robustness of onboard safety mechanisms, the importance of pilot decision-making under stress, and the need for continued engine reliability monitoring.
🇮🇳 4. IndiGo Emergency Landing in Mumbai (July 16, 2025)
An IndiGo A320neo, operating flight 6E‑6271 from Delhi to Goa, made an unscheduled emergency landing at Mumbai International Airport after the flight crew issued a “PAN PAN PAN” alert due to engine malfunction.
Key Details:
The mid-cruise alert indicated a serious but non-immediate emergency, allowing controllers to prioritize the aircraft for a safe landing.
All 191 passengers and crew disembarked safely, and the engine in question—a Pratt & Whitney PW1100G—was taken offline for forensic analysis.
IndiGo’s maintenance team, along with Pratt & Whitney representatives, are conducting a joint diagnostic review.
Broader Context:
The PW1100G engine model has been under scrutiny globally for compressor and bearing durability issues, with several airlines facing grounding advisories and maintenance delays.
The incident may trigger renewed audits on engine health monitoring systems and component life-cycle tracking across the A320neo fleet in India.
🛩️ 5. Zeusch Aviation Crash at Southend Airport, UK (July 13, 2025)
A Beechcraft Super King Air 200 aircraft, registered PH‑ZAZ and operated by Dutch charter firm Zeusch Aviation, crashed shortly after takeoff from London Southend Airport, resulting in the fatalities of all four individuals onboard.
Key Details:
The aircraft had just departed for a medical transport mission when it lost altitude and crashed into an adjacent field approximately 1.2 nautical miles from the runway.
Weather conditions were reported as clear, and ATC recordings did not indicate any distress call prior to impact.
Investigation Status:
The UK’s Air Accidents Investigation Branch (AAIB) is leading the technical inquiry. The wreckage is being examined for signs of mechanical failure, control surface anomalies, or fuel system disruption.
Pilot medical records, flight history, and aircraft maintenance logs are also under forensic scrutiny.
Preliminary findings are expected by early August, with a full report likely by year-end.
Implication:
As the deadliest King Air crash in the UK in recent memory, the accident underscores the risks in light twin-turboprop operations, especially during initial climb-out phases.
Industry experts emphasize the importance of engine-out training, departure briefings, and strict weight-and-balance adherence in charter operations.
