NTSB discusses reason for Dali collision with Key Bridge

Federal investigators are reviewing the results of the investigation into the collapse of the Francis Scott Key Bridge in 2024. The National Transportation Safety Board recently gathered to discuss the likely causes of the incident, safety suggestions, and any adjustments to their initial report from May. During the hearing, NTSB Chairwoman Jennifer Homendy expressed that the tragedy was preventable and thanked all those who responded to the incident. The NTSB overviewed various factors, including the ship's electrical components, data recorders, bridge safety, and actions taken during the emergency. One of the key findings was that a loose signal wire caused electrical issues on the ship, leading to the blackout and eventual collision with the bridge. Additionally, investigations revealed challenges in accessing data from the ship's voyage recorders. The NTSB also evaluated the response protocol during the emergency, pointing out the ineffective actions taken due to the vessel losing propulsion. Furthermore, the NTSB discussed bridge safety and highlighted missed opportunities in assessing the bridge's vulnerability. The timeline of communication leading up to the incident was outlined, emphasizing delays in warning highway workers about the emergency. The investigation continues as Maryland officials update the estimated cost for replacing the bridge.
