Alaska airlines flight 352 Flight 352, operated by a Boeing 737-900ER aircraft, experienced unexpected turbulence as it descended through an altitude of approximately 9,000 feet, about 20 miles southwest of Seattle-Tacoma International Airport. The sudden turbulence caused the aircraft to violently shake, resulting in injuries to 23 passengers and crew members. The majority of the injuries were minor, such as cuts, bruises, and whiplash, but two passengers were transported to local hospitals for further evaluation and treatment. The aircraft, with 165 passengers and six crew members on board, managed to land safely at Seattle-Tacoma International Airport, where emergency medical services (EMS) and airport personnel responded to the scene. The injured passengers and crew members were immediately evaluated and treated, with some receiving additional care at nearby hospitals. The FAA and NTSB launched separate investigations into the incident, focusing on various factors such as weather conditions, aircraft maintenance records, and crew training. Preliminary findings suggest that the turbulence was caused by a rapidly developing low-pressure system, which is often referred to as a "jet stream." These powerful air currents can reach speeds of up to 200 miles per hour and are capable of causing significant turbulence, especially when aircraft encounter them unexpectedly. In response to the incident, Alaska Airlines issued a statement expressing their concern for the affected passengers and crew members and reaffirming their commitment to safety. The airline also implemented additional safety measures, such as increased communication with flight crews regarding potential turbulence and enhanced training on responding to in-flight medical emergencies. The incident involving Alaska Airlines Flight 352 serves as a reminder of the importance of seatbelts during all phases of flight, even when the seatbelt sign is not illuminated. It also highlights the need for continuous improvement in weather forecasting and turbulence prediction technologies to minimize the risks associated with in-flight turbulence. Irving, Texas is a vibrant and diverse city located in Dallas County, with a population of over 240,000 residents. It's home to several major corporations, including ExxonMobil and Fluor Corporation, and is also the site of the Las Colinas community, which is one of the first master-planned developments in the United States.
