A B-52 bomber crash during a test flight at a U.S. Air Force base in California kills eight people aboard, according to multiple outlets. Early flight tracking data available after the incident shows the aircraft turning shortly after takeoff, making a sharp right-hand maneuver and then nearly completing a 180-degree turn. The aircraft subsequently plunges to the ground at a rate described as nearly a mile per minute (or about more than 1,500 meters per minute), based on limited tracking information reported by outlets citing data providers such as AirNav Systems. The crash occurs shortly after takeoff, and officials say the cause has not been determined. Reporting indicates that investigators are likely to take an extended period before they complete their assessment, with one outlet noting that the investigation could take up to six months. Across the coverage, there is agreement on the number of fatalities and the main features of the aircraft’s path and descent as reflected in the limited tracking data, while the underlying cause remains under investigation.
