Whiteknight...that 'two at once' or 'blocked' transmission at Tenerife was definately the most fatal aftemath of such an incident. Not sure if the KLM Captain would have stopped, though. He seemed determined to go that day.
583 fatalities actually; still the most tragic accident in aviation history. I was 12 years old when it hapened, and will never forget it, nor its lesson to me as a pilot.
