当地时间11月20日，美国国家运输安全委员会（NTSB）表示，10月16日，美国联合航空公司1093航班 在飞行途中疑似遭到一个气象气球撞击，飞行员在紧急降落前被驾驶舱风挡玻璃碎片击中。 这架波音737 MAX客机10月16日从美国丹佛起飞，载着134名乘客和6名机组人员飞往洛杉矶。在约1万 米高度巡航时，飞机风挡玻璃破裂，不过机舱并未失压。最终，飞机在盐湖城紧急降落。 （文章来源：央视新闻客户端） 加利福尼亚州知名气象气球设计与运营企业御风系统公司上个月表示，他们认为其生产的一个气球击中 了美联航1093航班。 美国国家运输安全委员会表示，该气球的雷达轨迹与被击中的联合航空客机吻合，撞击"导致两名飞行 员被玻璃碎片击中，机长右臂有多处表皮擦伤"，副驾驶未受伤。 ...

Group 1 - A United Airlines Boeing 737 MAX experienced a windshield failure during cruise, leading to an emergency landing in Salt Lake City, likely due to a collision with a weather balloon [1][2] - The weather balloon involved was operated by a California-based company, which has launched over 4,000 balloons that comply with FAA regulations [2] - The CEO of the balloon company expressed concern over the incident, noting that the balloon's weight was only about 1 kilogram, and the company is investigating ways to reduce impact force in future incidents [2][3] Group 2 - The balloon company has adjusted its software to minimize the time balloons spend at altitudes between 9,000 and 12,000 meters [3] - The company is also researching different ballast designs to lower the potential damage to aircraft and reduce the risk of injury in case of a collision [3]

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]
