Federal aviation safety investigators release a preliminary report on a June 14 crash involving a skydiving aircraft in Missouri that killed 12 people aboard, including 11 skydivers and their pilot. According to multiple outlets summarizing the report, investigators did not identify any serious safety failures before the crash that could explain the fiery impact. The reporting states that the preliminary findings did not flag engine failure as a contributing cause. The accounts also indicate that investigators have not found evidence of a major safety lapse that would account for the circumstances leading to the disaster. One outlet notes that the jumpers included several experienced skydivers. Overall, the sources describe the preliminary stage of the investigation, emphasizing what it does not show—no major safety failures or engine-related issues identified in the early review—while leaving open that further analysis may still be conducted as investigators examine additional data and materials related to the aircraft and the flight.
