上圖拍攝於1943年11月22日，圖中美國軍方稱為Toyohara（豐原）的機場實際上是被日本人稱為台中飛行場，但是此台中飛行場並非目前已廢棄的水湳，而是空軍清泉崗基地的所在地。下面這張1944年3月1日的傾斜空照雖然被中研院加了浮水印，但畫質較佳。
The above annotated photo was taken on November 22, 1943, and was later used in the intelligence analysis Formosa Interim Report, February 1944. The airfield in the photo, Toyohara, was in fact referred to by the Japanese military as Taichu. The oblique photo below, taken on March 1, 1944, has better quality.

1944年10月15日，由B-29轟炸機改裝的美國陸軍航空隊第468轟炸大隊偵察機拍下了下面這張傾斜空照，在台中飛行場（Toyohara A/F）的西方多了一座附屬機場（Satellite A/F）。美軍分析人員判讀這座建造中的機場有一條東北－西南走向的跑道，長3800英呎，寬200英呎，還有長約6000英呎的滑行道，並可透過另外一條滑行道與台中飛行場相連。
On October 15, 1944, the 468th Bombardment Group of the US Army Air Force took the following photo of the same area. A “satellite airfield” had been built to the west of Toyohara Airfield. An intelligence report, dated February 15, 1945, described the satellite airfield as having a NE-SW 200′ x 3800′ runway, a 6000′ taxiway east of runway, and another taxiway connecting it with Toyohara Airfield. The airfield was described as under construction at the time.

當美軍在1945年7月5日拍攝以下照片時，上圖中的附屬機場看來已經大致完工。
By the time when the next photo was taken (July 5, 1945), the satellite airfield (pointed by the arrow) most likely had been completed.

照片放大後可以看到跑道兩頭供飛機迴轉的turning circle可由滑行道連接：
The enlarged photo below shows that the airfield had two turning circles on either end of the runway and a taxiway connected the two turning circles and the middle of the runway.

二次大戰結束後，日軍呈繳給國軍的飛機場要圖裡，這座美軍所謂的附屬機場被畫成台中飛行場的一部分，所以稱它為台中飛行場的西跑道也不為過。後來台中飛行場成為空軍公館基地，在美軍的協助下大幅擴建與加強，所以在下面這張1959年的空照裡，這條西跑道幾乎已經看不見：
After WWII, Toyohara Airfield (officially Taichu Airdrome) was taken over by the ROC Air Force and became Kung Kuan Air Base. Wit the aid from the US military, the base was greatly expanded and enhanced. In the following 1959 photo, covering the same area as that in the above photo, the old satellite airfield had all but disappeared.

公館基地後來改稱清泉崗，而原來台中飛行場西跑道的位置現在變成的台中航空站的用地，政府應該在此立碑（或牌）說明。以下是我在Google Maps上繪出的台中飛行場西跑道：
Kung Kuan Air Base was later renamed Ching Chuan Kang (CCK). The location of the old satellite airfield is currently used by Taichung Airport, as can be seen in the following overlay on Google Maps:
