ultrasonic 復習

The National Transportation Safety Board is finishing up its initial examination into the deadly Southwest Airlines engine failure Thursday -- but many questions remain unanswered.
Investigators can't explain with certainty why the left engine of Southwest Airlines Flight 1380 malfunctioned when the plane was reaching over 32,000 feet. It's too soon to determine what happened, said National Transportation Safety Board Chairman Robert Sumwalt.

今回調べた単語はultrasonic / ʌ̀ltrəsɑ́nɪk /です。『ジーニアス英和辞典』(第四版,大修館書店)には「超音波の」とありました。記事によると、12月に超音波検査が行われるはずだったようです。検査不足だというのが今回の原因ではないかと感じました。
個人的にはultrasonicの発音に気をつけたいところです。カタカナ読みをしないように心がけなくてはと思います。(rain)
