Live video footage captured by a Los Angeles TV news helicopter moments before it crashed is considered "the most important evidence" by investigators seeking to determine the cause of the deadly incident. The National Transportation Safety Board (NTSB) stated Wednesday that the video from NBC Los Angeles helicopter reporter Eliana Moreno and pilot George Marciniw is critical to their ongoing investigation.

Investigator-in-charge Fabian Salazar detailed the importance of the recovered recording, explaining that it clearly shows the helicopter shaking and alarms sounding in its final moments. The feed abruptly cuts off after a voice is heard asking, "You can't pull up?" The crash occurred Tuesday evening in Chatsworth, a neighborhood in Los Angeles, during a news gathering operation.

Salazar indicated that the recording will undergo a detailed sound spectrum analysis at the NTSB's recorders lab. "We are clearly hearing sounds that are consistent with the engine changing its speed," Salazar said, adding that the audio also includes tones likely serving as advisories to the pilots. This analysis aims to pinpoint any mechanical or operational issues that may have contributed to the crash.

The crash claimed the lives of reporter Eliana Moreno, pilot George Marciniw, and a 29-year-old person on the ground, identified as Edy Gutierrez Mejia. A fourth individual sustained injuries and was transported to a hospital. NBC Los Angeles confirmed that Moreno and Marciniw had extensive experience working together, having logged hundreds of flight hours on assignments, including coverage of the wildfires in January 2025.

The NBC Los Angeles helicopter was among several news aircraft in the vicinity at the time, all covering a separate fatal collision between a Metro bus and an SUV that had occurred approximately two hours prior. Authorities reported that the bus and SUV crash resulted in two fatalities and several injuries. The driver of the SUV, Bailee Lynn Rios, is facing charges of murder in connection with that incident.

Investigators are meticulously examining the wreckage of the Eurocopter AS 350 B2 helicopter at the crash site. The NTSB is focused on gathering all available data, including flight recorders, maintenance records, and witness accounts, to reconstruct the events leading up to the fatal crash.

Community members have begun to gather at Whiteman Airport in Los Angeles, where the helicopter was based, to pay tribute to the victims. Memorials have been established at the site where their helicopter was parked, reflecting the impact of the loss on colleagues and the wider community.

The NTSB's preliminary findings are expected to provide initial insights into the crash dynamics, though a comprehensive report detailing the definitive cause will likely take several months to complete, involving extensive analysis of all collected evidence.
