The Aviatik D.III was a German prototype single-seater fighter plane from the First World War, designed by Aviatik.
 It became the basis for the Aviatik D.IV and Aviatik D.V.
 In November 1917, the plane was first flown, using a 195 hp Benz Bz IIIbo gearless engine.
 It was of similar design to the Aviatik D.II, and was armed with two LMG 08/15 machine guns.
 After several tests at Adlershof from February 9–12, 1918, the plane underwent modifications, as requested by the Idflieg.
 In April, a second prototype, powered by a Benz Bz IIIbm, although several D.III powered by the original IIIbo engine were already under production; however, none of them were ever completed.
"Kampfgeschwader" 55 "Greif" (KG 55 or Battle Wing 55) was a "Luftwaffe" bomber unit during World War II.
 was one of the longest serving and well-known in the "Luftwaffe".
 The wing operated the Heinkel He 111 exclusively until 1943, when only two "staffeln" of its four "Gruppen" (Groups) used the Junkers Ju 88C.
El Al Flight 253, was a Boeing 707 en route from Tel Aviv, Israel, to New York City, United States when it was attacked by two Palestinian terrorists as it was about to depart from a layover in Athens, Greece on December 26, 1968.
 One passenger, Israeli Leon Shirdan, 50, of Haifa, a marine engineer, was shot dead.
 He was survived by his wife and then 15-year-old daughter.
 Two unidentified women were injured, one by a bullet, the other as she leaped from the jet when the door was opened.
 The two terrorists were 19-year-old Naheb H. Suleiman, born in Tripoli, Libya, of Palestinian parents, and 25-year-old Mahmoud Mohammad Issa Mohammad, born in 1943 in Palestine.
 They were members of the Lebanese-based militant organization Popular Front for the Liberation of Palestine The two Arabs dashed out of the transit lounge of Athens Airport just as the Israeli plane, parked 200 yards away, was preparing to take off.
 The plane had flown in earlier from Tel Aviv.
 Mahmoud Mohammed Issa Mohammed fired at the plane for more than a minute with a submachine gun, killing one; while the other threw two hand grenades, creating panic aboard the plane carrying 10 crew members and 41 passengers.
 The two men were taken into custody by Greek authorities.
 Mahmoud Mohammed Issa Mohammad, was sentenced to 17 years and 5 months behind bars.
 He was freed after less than 4 months after another Palestinian terrorist group hijacked a Greek airliner and demanded his release.
 Subsequently he successfully hid his terrorist past and emigrated to Canada.
 Once Canadian authorities learned of his crime, a protracted extradition process culminated in his extradition to Lebanon in 2013.
Theodor Rowehl (9 February 1894 – 6 June 1978) was a German pilot who founded the Luftwaffe's strategic air reconnaissance programme, and headed what became known as the Rowehl Squadron and became Kampfgeschwader 200 after his resignation in December 1943.
The jointer plane (also known as the "try plane" or "trying plane") is a type of hand plane used primarily to straighten the edges of boards in the operation known as jointing.
 A jointer plane may also be used to flatten the face of a board.
 Its long length is designed to 'ride over' the undulations of an uneven surface, skimming off the peaks, gradually creating a flat surface.
 In thicknessing or preparing rough stock, the jointer plane is usually preceded by the fore plane or jack plane and followed by the smoothing plane.
"Kampfgeschwader" 100 (KG 100) was a Luftwaffe medium and heavy bomber wing of World War II, and the first military aviation unit to use an unpowered precision-guided munition in combat to sink a warship on 9 September 1943 with the destruction of the  , in the first successful use of the Fritz X armor-piercing, gravity PGM ordnance.
Sturzkampfgeschwader 3 (StG 3) was a "Luftwaffe" Dive bomber-wing of World War II.
 It was formed on 9 July 1940 in Dinard from the "Stab/Kampfgeschwader 28" and redesignated to "Schlachtgeschwader 3" on 18 October 1943.
Bernhard Jope (10 May 1914 – 31 July 1995) was a German bomber pilot during World War II.
 He was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves of Nazi Germany.
 As part of Kampfgeschwader 40 (bomber wing), Jope flew missions across the North Sea and Atlantic Ocean in support of the German navy, damaging in October 1940 the RMS "Empress of Britain" .

The Fiat G.55 "Centauro" (Italian: "Centaur") was a single-engine single-seat World War II fighter aircraft used by the "Regia Aeronautica" and the A.N.R. ("Aeronautica Nazionale Repubblicana") in 1943–1945.
 It was designed and built in Turin by Fiat.
 The Fiat G.55 was arguably the best type produced in Italy during World War II, (a subjective claim also frequently made for the Macchi C.205 Veltro as well as for the Reggiane Re.2005 "Sagittario") but it did not enter production until 1943, when, after comparative tests against the Messerschmitt Bf 109G and the Focke-Wulf 190, the Luftwaffe itself regarded the Fiat G.55 as "the best Axis fighter".
The Heinkel He 111 was a German aircraft designed by Siegfried and Walter Günter at Heinkel Flugzeugwerke in 1934.
 Through development it was described as a "wolf in sheep's clothing" because the project masqueraded the machine as civilian transport, though from conception the Heinkel was intended to provide the nascent Luftwaffe with a fast medium bomber.

Question: Where was the plane flown by Kampfgeschwader 55, exclusively untill 1943, designed?
Answer: Heinkel Flugzeugwerke
