What steps do investigators take after a plane accident?

After a plane accident, investigators first access the wreckage and prioritize recovering the black boxes, which include voice and data recorders. These devices provide crucial information about what happened during the incident. Investigators also interview both pilots to understand their perspective on the events that transpired. This combination of physical evidence and firsthand accounts enables investigators to develop a comprehensive understanding of what went wrong and why the accident occurred. This methodical approach helps create a clear picture of the incident's causes.
