ADIZ紀錄串：今天首次貼海飛行的共機擾台。

「即使共機高度只有30公尺，仍遭我空軍發現，並執行廣播驅離。西南空域說，這展現我空軍雷達幾乎無死角，但相對地也有可能是共機用無人機侵擾，試圖找出我空軍雷達死角。」

中國船隊盜挖海砂的潛在軍事目的:

"中國之前不斷在台灣淺堆附近，大舉盜採砂石，有立委質詢軍方這可能有國安問題，還被海軍嘲笑，許多國人也頗不以為然。但是你現在將台灣淺堆的位置，套繪在中國軍機侵擾台灣空域的航跡圖上，你還能說這是巧合嗎??

（如果要我猜的話，我覺得中國很可能在疏濬水道，挖設一個水下伏擊區。）"

越看越覺得水下伏擊區這猜測可能是真的。

[ Detecting foreign underwater activity in and near the shallow Bashi Channel offers arguably the best and first line of defense against any foreign submarine intrusions, before they are able to reach the PLA’s South China Sea “bastion.” As part of China’s anti-access strategy, the control of the entrance points – straits and channels – is of critical importance. In the big picture, therefore, it is not surprising that Chinese aircraft patrol frequently near the Bashi Channel in the south and Miyako Strait in the north. For these reasons, China is likely to continue or, even, increase its maritime surveillance activities within the southwestern part of Taiwan’s ADIZ, near the Bashi Channel, and other critical sea lines of communications along the first island chain in the future, regardless of the geopolitical status of Taiwan.]
