I personally don't understand how anyone could possibly be able to work a crash scene. I know all of the different crews (fire and rescue, paramedics, NTSB, FAA, etc.) have to do their jobs, but how can one possibly function in all that carnage??? I would be haunted for life and have nightmares every single time I slept after seeing it. Fortunately Hartsfield, here in ATL, hasn't ever had a crash that I know of. I'm knocking on wood and praying that it will never happen.
