NBC4's helicopter was one of several news aircraft flying over the scene of a deadly bus crash in Chatsworth Tuesday evening at sunset.
It's common for multiple news choppers to arrive at the scene of breaking news, beaming live images for newscasts and streaming.
But around 7 p.m., something went horribly wrong and in a matter of seconds the NBC4 chopper dropped out of the sky, crashing into shipping containers and vehicles outside a warehouse a few blocks away, bursting into flames. Two station journalists, reporter Eliana Moreno and pilot George Marciniw, were killed along with a bystander on the ground.
Federal investigators are now trying to figure out what went wrong. The Times interviewed several experts, who reviewed recordings of the chopper's final moments. They offered insights into the helicopter itself, its movements that afternoon and what is known about how its mechanics work.
Here's what they had to say:
