M: Did you hear about the air crash that occurred in South America recently? It was quite a tragic accident!
W: No, I didn’t see anything in the news about it. What happened?
M: A foreign airliner was attempting to land at night in a mountainous area of Argentina and flew into a hill!
W: That sounds really terrible! Did anyone survive?
M: No, everyone aboard, including the crew, was killed instantly.
W: (1)___________________________?
M: Apparently, there were some low clouds in the area, but mostly it was just miscommunication between the pilots and the air traffic controllers.
W: Weren’t they both speaking in English, the official international aviation language?
M: Yes, they were. But the transmission from poor quality radios was slightly distorted(2)_____________________________.
W: How could a misunderstanding like that caused such a serious accident?
M: The pilots were told to descend to two-two thousand feet. The instruction actually meant 22,000 feet, but they thought they heard descend to 2,000 feet. That’s a huge difference, and it should have been confirmed, but it was not. Unfortunately, the terrain of the mountains in Norweija extends up 20,000 feet.
W: So the pilots did descend to the wrong altitude then, thinking they were following the air controllers’instructions.
M: Sadly enough, yes they did. It was a really bad mistake. Many people died as a result of the simple misunderstanding.
W: Wow, (3)_______________________________.
