Text Notes
 

 

Activities during the war

04-30 January 1942

The Kong Bin Noi Phasom (Combined Wing) 80, newly stationed at Chiang Rai,[13] sent Vought Corsairs and Curtiss Hawk IIIs from Squadrons 22 and 41 to scout and bomb the enemy in various locations in Burma and to patrol the skies over Mae Chaem, Mae Sariang, Khun Yuam, and Mae Hong Son.[13a]


07 January 1942

Sgt Pilot Victor Bargh, a New Zealander, in Royal Air Force (RAF) 67 Squadron, flew a photo-reconnaissance mission from Mingaladon, over Mae Sariang.[13b]

 

21-22 January 1942

[RAF 113 Squadron] Blenheims bombed Raheng and Mesarieng on the 21st and 22nd, dropping 6,000 lb of bombs on each target.[14]


28 February 1942

The Indian Air Force (IAF) made a surprise strafing attack on Mae Sariang.[14a]


January 1944

Allied intelligence issued a so-called "airfield miniature" of Mesarieng airstrip:[15]

"Cat D" (Category D) refers to "Fair weather only".
"400 Yds" (437 m) can fit with the 1944 overlay.

An early amendment to an Allied intelligence report:[16]

Amendment of January 1944

Transcription

MESARIENG: Under Remarks delete: "but has been possibly extended to accommodate military aircraft."

Note: the sheet to which this applies is not available.


January 1944

This aerial photo, taken in January, was only published in the April 1944 issue of Airfield Report. While of poor quality because of microfilming, it is the only WWII aerial photo of Mae Sariang available to the present:[17]

Another section of that report in April 1944 made an observation significant for the entire history of the Mae Sariang airstrip during WWII:[19a]

Intentional neglect of Mae Sariang airfield

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

05 March 1945

According to Mr Porm Sootsukon (a civil servant in Mae Hong Son) around 1235 hours on 05 Mar 1945, a single two-engined Allied Forces plane from the direction of Burma flew over the Mae Sariang governor's official resident and then went on . . . . It was assumed that the intent . . . was just psychological in support of the Free Thai movement.[24]


20 March 1945

". . . the fighter squadrons of the 2nd Air Commando Group flew to northern Thailand to strafe fields at Chiengmai and [Phrae][25], which were being used by the Japanese as air staging posts. Near Chiengmai Capt William C Marshall of the 1st Command Squadron encountered a small single-engined aircraft which he identified as a 'Stinson-type' and shot it down. It was in fact a civilian Fairchild 24 of the Aerial Transport Company of Thailand,[25a] which was unfortunate enough to have arrived at exactly the same time as the US fighters."[25b]


20 March 1945(?)

The pilot who flew the Norseman regularly from Chiang Mai to Mae Hong Son before the war, was a Mr Puai. Local people called the aircraft "Mr Puai's aircraft".

During the war, Mr Puai was shot down by an Allied aircraft while flying to Mae Sariang. The company and local people as well as his family were saddened to lose a good and friendly pilot.[26]


20 March 1945(?): another version, badly garbled

Interviewee No. 8, Mr Boon-ton Sriwichai:

After [?] the war, there was a Thai mail plane (for letter delivery from Mae Hong Son to Amphoes Khun Yuam and Mae Sariang). This plane flew three times a month. One day this mail plane encountered British aircraft flying in the opposite direction. The British pilots saw the Thai pilot and mistook him for a Japanese. Later the mail plane encountered 40 – 50 British planes, two of which turned and attacked. The mail plane caught fire and crashed in the Ban Mae Surin area.

Villagers went to see the plane crash site and found four dead bodies. They included the pilot, Mr. Pui (surname unknown); a pilot assistant (name unknown); a Japanese soldier in uniform; and the superintendent of Mae Hong Son. The next day, the bodies were ceremonially cremated. The remains of the Japanese soldier were taken to Japan. There were some burnt banknotes (about 10,000 baht), two pistols, and other belongings in the crashed plane which district officers took.[27]


April 1945

Amendments to Airfield Lists: SIAM: Amendment List No. 1 (1945):[28]

Amentment of Apr 1945 to Intel Reports

Transcription:

MESARIENG L/G: Landing Area: Amend to read:
Single strip: NE-SW, 1000 x 55 yards approx.

Apparently this item amends the report dated 31 December 1944 here.


??? 1945

. . . [apparently in late 1945] seven planes, guns firing, dropped
24 bombs, which fell in arice field behind Mae Sariang City Hall.
Four failed to explode. Nobody died.[29]


Through 15 August 1945 (end of war)

For record purposes, as of July 2012, good quality World War II era aerial photographs of the Mae Sariang area have not been found.


1977

View of the condition of the airstrip by a member of the 1977 Japanese team searching for I J A remains:

. . . on the eastern side of the "airfield." I say "airfield": it is only a narrow field where the red clay is raked and flattened. All around seems to be a second-growth forest of teak; weeds and bushes are grown out to about one or two meters.[29a]


1990

The movie, Air America, was released in 1990; it had used the airstrip at Mae Sariang in some of its scenes.[29b]


1992 / 2007(?)

Royal Thai Survey Department Map No. 4545 II, Title: Mae Sariang:

AIRPORT CURRENT STATS[31]

Name: Mae Sariang Airport - VTCS4
Coordinates: N18°11.3 E97°55.7
Runway Heading: 01/19
Length: 1,000 meters
Slope: none
Elevation: 750'
Obstructions: Clear.

The Thai Flying Club webpage for Mae Sariang Airport features two excellent oblique photos of the site; unfortunately, directions of photo views are less than clear: the smaller oblique photo (bottom left) dated 2003 looks south per Club comment; but the larger oblique dated 2007 looks north (note that the near end of the runway is labeled "01"). The webpage incorrectly identifies the river just to the west as the Salween; in actual fact, it is the Yuam. The Salween is about 27 km west.

The Thai Flying Club's two oblique photos of the runway also demonstrate that it was paved sometime between 2003 and 2007.

25.^ Shore identified Phroe: that name does not appear on Thai maps. Similar in name in the area were Phrao, Phayao, and Phrae. Only the last had an air facility (N18°08 E100°10), 60 km ESE of Lampang and shown on US Army Series L509, NE 47-7 "Lampang".

25a.^ "Stinson-type" aircraft: the Stinson SR-series was popular before the war per Wikipedia's Stinson Reliant, but that reference does not list any models in Thailand.

Mentioned in a following version: The Noorduyn Norseman. ". . . it looked surprisingly like the Stinson SR 10." per RCGroups.com's Noorduyn U-64 Norseman.

However, "Until 1940, the Noorduyn company had sold only 17 aircraft in total, primarily to commercial operators in Canada's north and to the Royal Canadian Mounted Police." per Wikipedia's Noorduyn Norseman.

On the other hand, Thai Aviation Net's Thai Civil Register and Royal Thai Air Force listing record no Norseman or Stinson models registered before the war; but the civil register does record a Fairchild 24 exported to Thailand 04 Oct 1940 (that particular aircraft survived at least until 1955) and its Air Accidents list records a Thai Air Force Fairchild 24 shot down in Mar 1945 by a USAAF P-51.

It would appear that the aircraft could only have been a Fairchild 24 as Shores asserts.
