美联航客机巡航途中风挡破裂 或因撞上气象气球

Group 1 - A United Airlines Boeing 737 MAX experienced a windshield failure during cruise, likely due to a collision with a weather balloon [1] - The flight, carrying 134 passengers and 6 crew members, was en route from Denver to Los Angeles when the incident occurred at an altitude of approximately 10,000 meters [1] - The aircraft made an emergency landing in Salt Lake City, and initial investigations suggest the balloon was operated by a company named Weather Systems [1] Group 2 - Weather Systems has launched an investigation and found that the flight's position data matched the last known location of their balloon, which stopped transmitting signals around the time of the incident [1][2] - The CEO of Weather Systems expressed concern over the incident, noting that the balloon's launch weight was only about 1 kilogram, which was surprising given the extent of the windshield damage [2] - The company has adjusted its software to reduce the time balloons spend at altitudes between 9,000 and 12,000 meters and is exploring different ballast designs to minimize impact in future collisions [2]
