A tragic event on a Singapore Airlines flight from London to Singapore has come under scrutiny as new details emerge regarding the severe turbulence that led to one fatality and dozens of injuries. The incident occurred on May 20, 2024, during flight SQ321, which was operated using a Boeing 777-300ER. After encountering turbulence over southwest Myanmar, the aircraft descended approximately 6,000 feet, prompting the crew to divert to Bangkok, Thailand.

The report from Singapore’s Transport Safety Investigation Bureau (TSIB), released on May 19, 2026—two years after the incident—revealed critical insights into the circumstances leading to the turbulence. Geoffrey Kitchen, a 73-year-old British man, tragically lost his life due to heart failure linked to the event. A total of 79 individuals, comprising passengers and crew members out of 229 onboard, sustained injuries during this harrowing episode.
In the wake of the investigation, there are concerns surrounding the aircraft’s weather radar system. The report suggested that the severe weather responsible for the turbulence may not have registered on the in-flight radar. While investigators could not definitively conclude that a malfunction was at fault, they noted that the possibility “cannot be ruled out.” The radar manufacturer has claimed there was no evidence of a malfunction during subsequent tests.
Prior to the turbulence, the flight crew reportedly observed clear conditions in their immediate vicinity. However, the TSIB noted that the pilots’ subsequent actions were considered appropriate given the circumstances. A thorough examination revealed that between May 2023 and June 2025, there were 103 separate reports of issues with the weather radar on Singapore Airlines’ Boeing 777 fleet, with 12 instances recorded for the specific aircraft involved in flight SQ321.
Despite the pilots not spotting any concerning weather formations, additional data indicated that several other aircraft in the vicinity had reported extensive cloud cover. The investigation team expressed confusion over the flight crew’s failure to identify these prevalent weather conditions, noting their tactical decision-making during the turbulent episode.
The report specifically ruled out the possibility of “clear air turbulence”—a phenomenon notoriously difficult to detect through standard flight measures—and identified the cause as “convective-induced turbulence”, which is typically associated with storm-related cloud formations. Such turbulence is particularly common in tropical regions during thunderstorms.
Investigators discovered that just before the turbulence struck, the flight crew had contacted air traffic control in Yangon, Myanmar, to request a more direct flight path due to anticipated weather challenges. Despite the pilots’ assessments that they were initially unaffected by the conditions, they later accepted a different route that was in proximity to the site of the turbulence.
In response to the findings, Singapore Airlines has taken numerous steps to enhance safety measures across its fleet. This includes the introduction of electronic tablets to improve turbulence monitoring and additional training for flight crews focused on managing turbulence situations effectively. A spokesperson from the airline expressed sincere apologies to all those affected by the incident, acknowledging the traumatic experience endured by those onboard flight SQ321.
This incident highlights critical lessons about flight safety and the necessity for vigilance in monitoring changing weather conditions, even when initial observations may suggest clear skies. Both the TSIB and Singapore Airlines have emphasised their ongoing commitment to safety as they implement measures to prevent future occurrences of such distressing events.
As investigations continue, the aviation community reflects on the inherent risks posed by sudden weather changes, reiterating the importance of robust technological systems to support pilots and ensure passenger safety during flights. The fallout from this incident serves as a stark reminder of the potential hazards faced by airlines and the passengers they carry across the globe.
