Text Notes



January 1944

"Miniatures" were a feature of Allied Airfield Reports for a time, designed to provide a quick reference for pilots to as many as 150 air facilities on one page.[18a] This is a "miniature" for the Mae Hong Son airstrip.[19]

January 1944

An amendment to reporting in January 1944 was provided to supplement information about the Mae Hong Son airstrip.

There are two important points here:

1. Improvement activities seemed to be occurring, indicating the continued presence of IJA troops despite abandonment of the road project --- though this might have been the result of delayed information surfacing after 09 November 1942

2. Two wrecked sheds had been removed. The origins of the sheds is not (probably can never be) clear, but it would be reasonable to assume that this wreckage was left over from the air raids in early 1942 --- and was finally being cleared:[20]

February 1944

No activity at the airstrip was reported, a reflection (finally?) of the 09 November 1943 I J A decision to abandon the Thai-Burma road connection --- but also perhaps evidence of delays in processing data by Allied intelligence:[21]

April 1944

A formal introduction, including a map, was provided for the Mae Hong Son airstrip in Spring 1944.[22] Aircraft reported as "occasionally" present were almost certainly Aerial Transport Company mail planes:[22a]

A formal "spec" sheet for the airstrip was included:[23]

March 1944 report on Mae Hong Son


And a standard update on activities observed at the airstrip was included:[24]

April 1944 report on Mae Hong Son

That the obstruction provided by two craters on the main runway remained unfilled since  01 Feb 1944 suggests that the craters were the result of an Allied air attack after the last Airfield Report in January; however, there is no record of such. As well, the failure to repair the craters probably reflected changing priorities for the Thai Occupation Army as the I J A's invasion of India matured.


Another section of that report in April 1944 made an observation significant for the entire history of the Mae Hong Son airstrip during WWII:[24a]

April 1944 note that MHS had not been developed

Transcription:

It is interesting to note that the meagre line of landing grounds in close proximity to the Burmese border from Mae Hong Son to Mae Sot, including Khun Yuam and Mae Sariang, have not to date been developed. In view of their difficult lines of communication it is unlikely however, that they would be employed for any purpose other than emergency use so that some form of maintenance work is likely to be the limit of their attention.


July 1944

A follow-up three months later provided additional details on the airstrip:[25]
