  Latest email from Tom.... KAKI3152.. should know soon if your correct!

The day before yesterday, my mail failed delivery due to my mistake.  Sorry for that.  Regarding the subject,  next week I have appointment with the pilot engaged in the interception, who is now 89 years old and good shape in health.  His memorandum describes as follows:
 
1. B29
He participated in the interception of B29 over Singapore about 10 times from Nov. 1945 to Mar. 1945.
On Febuary 11 (may be Feb. 1) he waited the at the altitude of 6,000 meters, and started attack with full speed the leader plane of the 4 formation from the right front of the leader, which should not normally be done in this way, aware of hitting sound of bullets, kan kan kan ,to his plane (KI-43 Hayabusa-Oscar). The bullets hit the right 2 engines of the leader and white smoke changed to black, soon it changed to white. The plane started decending and escaped.  The plane did not down. After landing, he noticed that the plane received 8 bullets, and one of them hit a gauge. He learned later the B29 ditched in the Indian Ocean.
 
2. B24
Late in June he was at the Limboeng (Rinbun ? - pronounced in Japanese).  Intercepted with 2 Oscars B24 during period of June 3 - 29th. The B24 came for attacking transport ships. He dived from the left front  of the B24 and shot down. The B24 with black smoke downed to the sea.
 
After meeting with the pilot, I report you  the details.  Tom

Indeed, the details are enticing.  I have a feeling that we've IDed both lost aircraft. 
 
In Edward Young's new book, B-24 Liberator vs Ki-43 Oscar, the author states in his conclusion that "(f)rom the beginning of 1944 until the end of the war, the Ki-43 would manage to shoot down only one more B-24" after pilots of the type claimed 31 Liberators shot down over China and Burma in 1943.
 
The loss at Celebes may be this singular aircraft.
 

Gents..
 
Latest from Tom...
 

 
Today, I met Mr Toshio Seki (S.Sgt Seki) and talked about B29 and B24. He  agreed to release his name as you asked.
 
1. B29
 As described it before, the altitude of his Oscar was almost same with B29.
 The damaged B29 started decending, but he did not pursue it as he has to intercept next target.  Later, he learned that a Japanese intelligence source monitered communications exchange between  the B29 and the rescue unit that it ditched to the Indian Ocean. He does not,however, remember how soon  after interception.
 
2. B24
The bombing warning for  the Japanese transport ships at Maccasar port (Manuai) had been received well in advance so that 2 Oscars (S.Stg Seki and his comrade S.Sgt Suzuki took off from the Limboeng Airfield. There were 2 B24s in line (He thinks it was the first B24 intercepted). He thought the B24 went down to the sea, he is not sure. After returning to the base, his comrade, S.Sgt  Suzuki told him it was Seki's credit as Suzuki's machine guns malfunctioned.
 
With my conversation,knowing that the crews of these bombers are MIA and KIA, Mr. Seki feels very sorry for their fate,even though he had to do his duty as a soldier. He said that he always scared until he pull the trigger of the gun.
 
Nowadays, he talks to the audience of the sessions how awful the war is through his experiences in the battle fields. 
Best Regards, Tom
 

If we are correct that the B-24 was in fact 44-42431 (MACR 14925),   lost on 25 Jun 45,  a B-24M from the  2nd Bomb Squadron / 22nd Bomb Group then it went down on land, not in the sea.   KIA does not quite describe what happened to the crew.   Here are three newspaper articles related to the incident.

American Airmen Beheaded In Lonely Jungle Cemetery
Less than a fortnight ago exhumations made at alonely cemetery hidden from general view a few miles out of Makassar, capital of the Celebes, revealed further revolting Japanese crimes. The victims wereAllied airmen, whose bodies were headless. One skull was still blindfolded, and the ankles were bound.
A touring investigation party visited a native village of hovels known as Daja, about 12 kilometres from Makassar. A narrow track led from the main road for a mile and a half through bamboos, and in a small clearing was a Japanese execution and burial ground. There were 24 small ,wooden crosses, all unmarked, in  one corner of the area, but several unmarked graves were also discovered.      In one shallow grave, in the reddish earth, was a body with ankles tied thrice with blackened cord. It was crouched forward, knees up to chin,and clad in military trousers. A medical man and a dentist were with the visiting party, and for almost two hours they carried out the grim task of learning of life from death.  The trousers were those of an American airman. Medical opinion was that multiple blows, probably with as sword, had been rained on the victim. Two had severed the third cervical vertebra, another the right cheekbone, and another the first right rib bone. The American airman had been beheaded.  
Search for Evidence
From another slightly deeper grave,further human bones were recovered and skulls. The quiet cemetery began to yield its grim secrets. Nowhere was there a sign of a coffin. In one grave, only a skeleton was found. The head was missing. The cemetery in the lonely, quiet bamboo grove is one part of the terrible story. The earlier part of the record comes from Makassar itself. It was there that the Tokki Tai (naval Gestapo) had their Headquarters. At the rear of their residence they constructed small stone prison cells, just high enough for a man to stand, and with little room to swing an arm.  
Allied airmen captured in several adjacent areas were carried to the  cells and kept there after ill-treatment.  They were given a cell each.   There are bloodstains on the walls  One dying, starving captured airman had scratched: "God be with me, mother." in blood. Sooner or later one,  or two or more airmen were taken blindfolded and with legs bound to the unseen execution ground,  the cemetery in the bamboos.  But the prisoners were not taken quietly to their deaths, the Japanese made a festival of the executions.  Natives tell the story of convoys of armed officers and guards in cars and motor cycles, with a prisoner bound and blindfolded in an open truck, proceeding through Daja to the little cemetry.  From the examination of the skeleton and the position in which the body  of the American Airman was uneathed, the scene at the cemetery was reconstructed. The prisoner, surrounded by ghoulish Japanese officers  and guards. all heavily armed, was made to kneel at an open grave, still blindfolded, while a gleaming sword was swung ruthlessly upon his bared and bent neck.

   Quick response from Tom:

Re: B29  Mr. Seki had been thought the B29 ditched to the Indian Ocean, and the crews were rescued alive until our discussion we had yesterday.
 
Re: B24  According to his memory, the intercept was carried out over the  shore line so that he thought it downed to the sea.
 
Re: KI-43  The design of two tone mottle of brown and green varied depending on the time when the aircraft was delivered.  In another words, there was no single design painted in production.

... 2 Oscars (S.Stg Seki and his comrade S.Sgt Suzuki took off from the Limboeng Airfield. There were 2 B24s in line (He thinks it was the first B24 intercepted). He thought the B24 went down to the sea, he is not sure. After returning to the base, his comrade, S.Sgt  Suzuki told him it was Seki's credit as Suzuki's machine guns malfunctioned.

That's impressive.  The "Oscar" was not designed as a bomber interceptor and was lightly armed with but one pair of 12.7mm machine guns, roughly comparable to a pair of American .50 calibers.  While the gun could fire a highly explosive round often mistaken for a cannon shell, it carried only 250 rounds each and had a slow rate of fire.  To down a Liberator by a single Ki-43 is a feat.

Was mr. Seki with the 33rd Sentai flying Ki-43s from the Celebes?

Gents..
 
  Tom is in the process of translating the info supplied by all of you and putting it into print for Mr. Seki. When he presents it, he will  ask Seki to confirm what Unit he flew with.

Dear Bill-san
 
Received the picture of Mr. Seki's Oscar with thanks, and I gave  the copy to to him today. By knowing the fate of individual name of the crews he engaged with B29 and B24, he wished to express his deepest sympathy to the families concerned and pray for the crews to rest in peace, as he could not recognize their fate till he saw the MACR lists this time.
 
1. B-29  He attacked right front of the B-29 which started shooting about 1,000 meters ahead and the bullets hit his Oscar.  He started shooting about 500 meters to the B-29 with about 40 rounds each. When passed over he, at a glance, recognized a picture like human-being drawn on the nose of the B-29.  After returned the base, his Oscar counted 8 bullets,  big holes on each wing , one hit the gauge through the engine.
 
2. B-24  After interception of the B-24 he returned to his home base in Singapore. He stayed in Limboeng airfield just 10 days. There were only 3 Oscars in Limboeng including his Oscar.
 
3. The Oscar: He belonged to No 2 Chutai with blue colored bar on the vertical wing; White for No 1 Chutai and
Red for No3 Chutai.
 
Here, I am sending you 2 pictures of Mr. Seki who agreed to release this picture to US side.  He may, by any chance, visit the States although he is 89 years old but still studying at a college.  Any information of the 2 aircrafts he will appreciate very much.
