Question: Hans Jacobs designed a glider-seaplane called the "Sea Eagle" that was test flown by a woman born in what year?
Context: The DFS Seeadler (Sea Eagle) was a German flying boat sailplane designed by Hans Jacobs of the Deutsche Forschungsanstalt für Segelflug (DFS).  It was version of the 1935 DFS Rhönadler, with a new fuselage and strongly gulled wings to keep them clear from spray.  The aircraft was first flown in the summer of 1935, test piloted by Hanna Reitsch, and towed by a Dornier Do 12. Hanna Reitsch (29 March 1912 – 24 August 1979) was Germany's most famous female aviator and test pilot, starting in the early 1930s.  During the Nazi era, she served as an international representative for the regime. The white-bellied sea eagle ("Haliaeetus leucogaster"), also known as the white-breasted sea eagle, is a large diurnal bird of prey in the family Accipitridae.  Originally described by Johann Friedrich Gmelin in 1788, it is closely related to Sanford's sea eagle of the Solomon Islands, and the two are considered a superspecies.  A distinctive bird, the adult white-bellied sea eagle has a white head, breast, under-wing coverts and tail.  The upper parts are grey and the black under-wing flight feathers contrast with the white coverts.  The tail is short and wedge-shaped as in all "Haliaeetus" species.  Like many raptors, the female is slightly larger than the male, and can measure up to 90 cm long with a wingspan of up to 2.2 m , and weigh 4.5 kg .  Immature birds have brown plumage, which is gradually replaced by white until the age of five or six years.  The call is a loud goose-like honking. Hans Jacobs (30 April 1907 - 24 October 1994) was a German sailplane designer and pioneer.  He had been taught sailplane design by Alexander Lippisch, designer of many gliders during the 1920s and the 1930s.  As the head of the "Deutsche Forschungsanstalt für Segelflug" (DFS - German Research Institute for Sailplane Flight) at Darmstadt in the years before World War II, he was responsible for a number of highly successful designs, including the DFS Rhönsperber, DFS Rhönadler, DFS Habicht, DFS Weihe, DFS Kranich, and the DFS 230 assault glider.  Hans also designed a glider-seaplane, the "Sea Eagle", test flown by Hanna Reitsch.  In 1936, Hans developed self-operating dive brakes, on the upper and lower surface of each wing, for gliders.  He designed the DFS 230 used in the Battle of Fort Eben-Emael. The Honghe National Nature Reserve (HNNR), is a 218.35 km2 Ramsar Convention-designated site in Heilongjiang Province in northeastern China.  It was first established in 1984 as a provincial wetland reserve, and was upgraded to be a national nature reserve in 1996.  173 birds are known from the Reserve including protected species such as black stork, black-billed capercaillie, greater spotted eagle, the Kamchatkan or Steller's sea eagle, mandarin duck, Oriental white stork, red-crowned crane, white-naped crane, white-tailed sea eagle, and whooper swan. The Philippine eagle ("Pithecophaga jefferyi"), also known as the monkey-eating eagle or great Philippine eagle, is an eagle of the family Accipitridae endemic to forests in the Philippines.  It has brown- and white-coloured plumage, and a shaggy crest, and generally measures 86 to in length and weighs 4.7 to .  It is considered the largest of the extant eagles in the world in terms of length and wing surface, with Steller's sea eagle and the harpy eagle being larger in terms of weight and bulk.  Among the rarest and most powerful birds in the world, it has been declared the Philippine national bird.  It is critically endangered, mainly due to massive loss of habitat resulting from deforestation in most of its range.  Killing a Philippine eagle is punishable under Philippine law by 12 years in prison and heavy fines. The Air Force Test Center (AFTC) is a development and test organization of the United States Air Force.  It conducts research, development, test, and evaluation of aerospace systems from concept to deployment.  It has test flown every aircraft in the Army Air Force's and the Air Force's inventory since World War II.  The center employs nearly 13,000 people and controls the second largest base in the Air Force. The Sanford's sea eagle ("Haliaeetus sanfordi"), sometimes listed as Sanford's fish eagle or Solomon eagle, is a sea eagle endemic to the Solomon Islands.  The "sea eagle" name is to be preferred, to distinguish the species of "Haliaeetus" from the closely related "Ichthyophaga" true fish eagles.  The species was described in 1935 by Ernst Mayr who noticed that earlier observers had overlooked it, thinking it was a juvenile of the white-bellied sea eagle. The DFS Reiher (in English "Heron") was a single seat competition glider designed in Germany by Hans Jacobs and first flown in 1937.  The type won the last two German Rhön gliding championships before the start of World War II.  Six were factory produced. The DFS Rhönsperber, otherwise known as the Schweyer Rhönsperber or Jacobs Rhönsperber (in English "Rhön Sparrowhawk") was a single seat competition glider designed in Germany by Hans Jacobs and first flown in 1935.  For several years it was regarded as the best German sailplane and about one hundred were built.
