Pai Bridge

The Pai River bridge is often cited as the most visible evidence of the presence of Japan's Army in Northern Thailand during WWII.
But the statement is incorrect. This website attempts to resolve that error, as well as other misconceptions about the period.

Wat Phra Yuen: Crash site of Jack Newkirk, Flying Tiger Ace

Lamphun City area

Wat Phra Yuen,[1] just east of Lamphun Town, is notable in WW2 for having witnessed the fiery death
of Flying Tiger[2] Ace "Scarsdale Jack" Newkirk[3] in the crash of his P-40 on the morning of 24 March 1942.

Text Notes


Numerous accounts of the death of Jack Newkirk, Flying Tiger Ace, have been written over the years.[4]

Two recent versions appear in a 2009 exchange on Dan Ford's Warbird's Forum. As products of distillation offered by the passage of almost 70 years, hopefully they provide the most up-to-date and accurate information.

Dan first presented Jack Eisner's findings in Feb 2009:

Jack Newkirk, the view from the ground (Jack Eisner)
Photo-map of the crash site (Jack Eisner)

Then, in Apr 2009, Dan published a response from Bob Bergin:[7]

Jack Newkirk, was he shot down?, which includes excerpts from Bergin's:

Aviation History article, "Flying Tiger, Burning Bright", July 2008[9]

On the face of it, Jack Eisner's position makes more sense:

Bob Bergin acknowledges the eyewitness accounts on the ground which conflict with pilots' records about Newkirk's crash --- actually, per his account, Bergin learned of the views from the ground in 1994 as a part of a Flying Tiger reunion in Chiang Mai. However, he only published that information in 2008 with his Aviation History article; and Eisner did not learn of it and get a copy until late Dec 2008. While its absence resulted in some duplication of effort by Eisner, it was useful in that it forced Eisner to independently confirm --- and interpret --- the testimony of (now) very elderly residents about the crash. While details do differ in the two reconstructions, it is more the tenor of Bergin's article which favors the pilots' accounts of the crash over those of the people on the ground that catches a reader's eye, and his seeming effort to discourage further research. Bergin begins his last section with:

So what did happen to Jack Newkirk . . . at this point who can say, and I don't think it's fair to make that judgment now.[10]

Perhaps Bergin is implying that it could be disrespectful to the memory of Jack Newkirk to continue research that might point to a human flaw in a "legendary American hero". Such an attitude does, however, rather fly in the face of the concept of the orderly development of knowledge. In actual fact, such an attitude is foreign to the philosophy of the study of history:

The body of literature on almost any historical subject takes the form of an ongoing debate.[11]

Thus I think we are obligated to offer an alternate, informed, reasoned judgment after the event.


This is not intended to belittle the Flying Tigers' courage and capabilities in any way, but it is important to recognize that all the pilots were operating in a combat mode, under extreme stress. They had already made strafing runs on actual ground targets by the time they got to the area where Newkirk would crash. They were at that site for mere seconds and the actual circumstances leading to Newkirk's crash were not witnessed by any of them. The event was one of many on that flight, and that flight was one of many in which they had already participated. In this particular instance, the pilots' recollections were necessarily largely speculative. They needed to make sense of what had happened for their flight reports, but they were working with inadequate information.

Conversely, on the ground were a number of basically neutral observers, who were there for the whole of the sequence of events. Not only did they witness events surrounding the crash, they were there to see and possibly to participate in the subsequent cleanup. It was probably the closest any got to WWII combat (which was in contrast with serious air attacks on Chiang Mai,[12] 22 km to the north, and Lampang,[13] 60 km to the southeast). This single war-related event at Lamphun would have left a vivid impression on residents there.

I think it more logical to envision Newkirk, having been fired on by an anti-aircraft (AA) battery at the Ban Tha Lo railroad bridge, proceed to circle to make a run on the bridge to return fire and neutralize the AA battery. He would have planned to approach the AA battery as low as possible in order to get below the vertical range of those guns. During that run, as he was completing his turn to line up on the bridge, he was distracted by a "target of opportunity", just momentarily, but long enough so that he could not react in time to avoid a flame tree --- if he even saw it at all.[13a]

Events happen ever so quickly at 300+ mph (~500 kph). That's 440 feet per sec, a mile every 12 seconds (134 meters per sec, a kilometer every 8 seconds). Already at low altitude, diving further to treetop level. A distraction of only seconds. And during that distraction, a tree suddenly appeared in the flight path. The version of events that Jack Eisner suggests is quite plausible. And quite simple: Occam's razor[14] applies.


New facets

RTAF Lamphun Airstrip location

Subsequent to the postings in the Warbirds' Forum and the above review, more detail has surfaced with regard to circumstances surrounding Newkirk's fatal crash. Per an aerial photo in an Allied intelligence report (here annotated):[15]

Reoriented aerial photo of Lamphun airstrip


. . . a Royal Thai Air Force (RTAF) military airfield, the only airstrip recorded in the immediate Lamphun area during WWII, can be accurately located, and Jack Newkirk's flight path leading to his crash point more closely roughed in:[16]

Newkirk possible crash site

The airstrip --- existing at the time of Newkirk's fatal crash --- could be seen to neatly jibe with Thai recollections of:

1. A plane approaching from the southeast (to strafe the airstrip), and then
2. circling Lamphun (to strafe the AA installation at the bridge) before crashing at Wat Phra Yuen.

In addition, RTAF history confirms that the airstrip at Lamphun was attacked on the morning that Newkirk crashed:

On 24 March 1942, enemy Tomahawks bombed . . . Lamphun airport around 0700 hours. . . .[17]

More information may lie in Royal Thai Army records: the Thai Phayap Army's 35th Infantry Battalion had responsibility for protecting the rail line between Lampang and Chiang Mai at that time.[18]


Disposition of Newkirk's P-40[18a]

The wreckage of Newkirk's aircraft was collected in front of the Lamphun Police Station where it was photographed. Subsequently it was moved to the IJAF headquarters building in the occupied Wattanothaipayap School. From there it was sent to Bangkok by rail with no further record available.

A rumor that the wreckage was at some point put on display at Yupparaj School has proven untrue: after the war, the RTAF donated an old Allied aircraft for that rumored display which was near the southeast corner of the school property at the intersection of Ratwithi and Ratchaphakinai. The display, similar in appearance to those of aircraft around the Chiang Mai Airport today, was vandalized and pieces scavenged to the point that the aircraft eventually disappeared.[19] It was whole in 1980.[20]

See Lewis, Richard, "The Art of Strafing", Airforce Magazine, July 2007, esp paragraphs 11-13, which start "For most fighter pilots . . .". While the article deals specifically with the A-10 "Warthog", the same principles would apply to strafing with a P-40.

Another phenomenon which might have figured into Newkirk's crash was Motion-Induced Blindness.
