Boeing Model 281[/heading]
P-26 as one of the first mass-produced jednoplošných fighters, of course, awakened interest abroad, and the company Boeing has proposed an export variant, named Model 281. The first of two demonstration machines (with civil registration X12771) took off 2. August, 1934 and in principle it was the P-26A with different equipment (lacked e.g. the radio) and high back. Soon after the start of the tests showed the same problem with the high landing speed, what should the army of the machine, and the Boeing began work on the design of split flaps, which were after testing on the Model 281 adopted by the army and added to its the P-26A. The immediate interest shown by China, and already 15. September 1934 he traveled X12771 to Canton, where he was presented to the pilot E. R. Dorsleym. 28. November but Dorsley on the Model 281 killed in a crash at the airport Chungjao in Shanghai.

In addition to the high prices perhaps even because of this accident, the chinese aeronautical commission from any purchase subsided, interest but reflected the air force of the autonomous province of Guangzhou. In October 1934 it was issued a u.s. export license, however, the chinese central government imports, authorized in September 1935. The last of the ten purchased machines that were financed and collections in restaurants american Chinese, arrived in the Canton of 16. January 1936, and were here assembled a corporate staff under the guidance of Nemo Poncettiho, who then trained the staff chinese. One of the machines the manufacturer has equipped the modified fairing chassis, which was from the side open and together with the low-pressure balonovými tires Goodyear should allow better operation in field conditions. Boeing allocated the cantonese elite 2. squadron, where they served together with the .W.16 under the command of colonel Ting Ji xu. The coloring of the machines was at this time grey, with the characters only on the wings and black numbers 1-10 on the hull. The characters were unlike the machinery of the central government red edging.

The province of Canton (Guangdong) and Guangxi had at this time a very lukewarm relationship with the central nankingskou the government, and from the end of 1935 it was expected that the central government tries to local opposition to suppress it by force. She, however, decided to take the first step and after the armies of both provinces joined in the "Protijaponskou army of national salvation", in the spring of 1936 went to the north, and in June crossed the border of the province of Hu-nan. Basically even there have been no fights between the chinese factions, because a large part of the rebel forces immediately moved to the side of the central government. 7. June as follows přelétly to Nanking and three Boeing 281, together with four Douglasy O-2MC, but it was nothing against the events of 18. July, when all of a sudden dezertovalo all 136 of cantonese airmen to 72 aircraft, under the leadership of the commander of the air force Chuang Kuang-žueje! Both a rebellious province is soon subjugated. Short career Boeing in guangzhou air force so ended, and all ten machines were allocated to 17. squadron 3. fighter regiment of the chinese air force.

After the outbreak of the sino-japanese war 7. August 1937 was a Boeing 17. the squadron among the first machines that engage in the fighting. 17. the squadron was commanded by Wong Pan-yang, čínskoamerický volunteer from Seattle, and his deputy was Wong Sun-shui, originating in Los Angeles (we both came from the canton air force, and both in the united states used the name John Wong Sun-shui, however, had the nickname "Buffalo") and the squadron at that time was housed at the airport, Choo-jung near Nanking. Boeing have been at this time přebarvovány olive green on all surfaces, black numbers on the side was replaced by white numbers from 1701 after 1710. 15. August eight Boeing (together with five fiat cars CR.32, 12 Hawks II and Hawk III from 8., 28. and 34. squadron) occurred 20 bombers Mitsubishi G3M2 from Kisarazu Kokutai, leading to the main city. Captain Wong Sun-Shui on Boeing no 1703 reached the first victory in the battle of Nanking. The kill, shared with the Su Jing-Sienem, reached and Wong Pan-yang on no 1701, and another one reported Chun Cha-chu. Already the second day early in the morning G3M japanese Kanoja Kokutai carried out the raid on the airport of Chu-jung, the home of the 17. and 28. fighter squadrons, and in the subsequent fight Wong Pan-yang on its Boeing reached the other two kills, while Buffalo Wong made one bomber before he jammed machine guns, at least damage.

His second and last victory on the Boeing no 1703 reached Buffalo Wong 23. August, when near the island of Chong-ming shot down Nakadžimu A4N1, bad for him, but he ended the duel with eight Kawanishi E7K1 19. September, due to injury to the end of the year, perhaps in the fighting part of it. 22. September also occurred to captain Wong Pan-yang, whose Boeing 281 # 1706 was one of two chinese planes, which had to make an emergency landing after the collision with the japanese A5M. Wong and his Boeing, but at least got two kills, in cooperation and soon against the A5M waited for the retaliation. 12. October the Japanese attacked Nanking nine G3M, accompanied by eleven A5M 13. Kokutai. Against them was sent a mixture of two Boeings, six Hawk III and one Fiat under the leadership of colonel Kao Zhi-chang, and just Wong Pan-yang spotted the japanese planes first. At the first assault he managed to shoot down one A5M, perhaps even because of its inexperienced pilot thought was a monoplane Boeing for a japanese plane. The success he scored a second Boeing, piloted by Wong Ji-Jan. Although Boeing had to soon break away and leave everything on the Curtissech, the Japanese later hláslili that they were chinese "Bredami 27" surrounded by (the Breda Ba.27M it was a monoplane fighter, a very similar construction and the Chinese have used nine or eleven). The clash eventually ended up losing four A5M and the Japanese claimed six victories - Boeing and Curtissy were against the A5M outdated and numerically inferior, their pilots but they had much more experience.

This, however, was perhaps the last known conflict, which included the participation of Boeing 281, suffering from a lack of spare parts and poor maintenance, and 17. the squadron was soon re-equipped with Glostery Gladiator. When in December of 1937, Nanking fell, no Boeing no longer airworthy.

Other countries, which Boeing Model 281 used in the fight, it was republican Spain. 10. march, 1935, was the second demonstration aircraft, X12775, without the weapons supplied to the madrid Barajas airport and was then tested by the Spanish military pilots as a possible replacement for the main Spanish fighter type, Nieuport-Delage NiD.52. Followed by the similar situation is in China - although the performances of the Model 281 to the test pilots very impressed, Boeing has once again demanded to the Spanish budget too high a price, 500 000 pesetas, and the Spanish government, therefore, the purchase of 281 rejected in favor of the purchase of a license to Hawker Spanish Fury, which should be built by the company Hispano-Suiza in Guadalajara.

When 18. July 1936 began the Spanish civil war, the Boeing 281 was still at the airport Barajas. Therefore, it was immediately armed with two 7.7 mm Vickers machine guns mounted under the wings (the engine did not have the synchronizer) and deployed on the republican side. Served alongside Spanish Fury and Dewoitin D.372 at the airport of Getafe, and very soon he was one of the few! machines here - in October 1936 in addition to Boeing was the only one Fury and one Many. 21. October Boeing piloted by one of his former test pilots, Ramón Puparellim, flew to the defense of the airfield before the three rebel fiat cars CR.32, he was of course shot down, Puparelli time jumped. The Spanish government, however, the Model 281 never buy it, until later paid Boeing over the paris embassy $ 20, 000 as compensation.
