Text Notes
 


November 1943

"Miniatures" were a feature of Allied Airfield Reports for a time. Each miniature emphasized airfield configuration and alignment. They were designed to provide a quick reference for pilots to as many as 150 air facilities on one page. This is a miniature for the Lamphun airstrip:[8]

Lamphun miniature

"Cat. B" indicates "Believed [to be usable in] all weather".

The bearing of the airstrip would appear to be in error (see corrected aerial photo below).

The commentary below suggests that the IJA had assigned a low priority to the Lamphun airstrip until approximately November 1943. That date is significant because it implies that improvements to the airstrip were part of the preparations for support from Thailand for the IJA's planned 1944 invasion of India:[9]

From the same period is an aerial photo.[11] Key details are circled:

1. "Nuang River" which flows south through Lamphun town
2.  Railroad bridge (unlabeled) over Nuang River
3. "Bangkok Chiengmai R/y."
4. "Access Road"
5.  Airstrip (unlabeled)
6.  North arrow which is pointed 14° too far west

Lamphun airstrip wih corrected bearing

The correction is based on the known bearing of the straight section of railroad track marked with a yellow "center line" in the photo above. It is "known" because the track is still in use today.[13] With alignment of the aerial photo corrected,  it can be properly positioned, as shown on the location map on page 1.
