筆者住鄉下， 發現這些最高層， 八至十二公里高航線， M750 為例， 多種氣象下， 聲音仍明顯。 當然在都市則不明顯但增加噪音背景值。
The author lives in the countryside and has discovered these highest 8-12 km. high airways, e.g., M750, in most weather, are still quite audible. Even in the city, though not noticeable, they contribute to the total background noise.
惟如南投埔里等少數角落倖免， The only lucky exceptions are e.g., Puli in Nantou etc. few corners of Taiwan,
希望多些飛機由海線， 少些飛機由陸線。 One hopes more planes will routed over water and less over land. 希望多仿造中國 M503 全由海域！ One wishes more routes could be like China's M503 all water route!
另外， 所謂兩岸「直航」其實繞好大。 桃園至福州為例， 原 184 公里， 今 2013 年仍必繞總共 806 公里。 耗能、 時、票價、 碳排放。
In addition, the so-called "direct flights" between the two sides of the Taiwan Strait are in fact unimaginably circuitous. E.g., 806 km. are spent flying the 184 km. between Taoyuan and Fuzhou still as of 2013. A waste of energy, time, ticket costs, and carbon emissions.
赴廈門為例， 連出程雖無木馬之憂卻仍須繞 Example: looping even on the outbound leg to Xiamen, despite no Trojan Horse concerns: 圖 Map， 文 Text。
