Operation Gold (also known as Operation Stopwatch by the British) was a joint operation conducted by the American Central Intelligence Agency (CIA) and the British MI6 Secret Intelligence Service (SIS) in the 1950s to tap into landline communication of the Soviet Army headquarters in Berlin using a tunnel into the Soviet-occupied zone. This was a much more complex variation of the earlier Operation Silver project in Vienna. The plan was activated in 1954 because of fears that the Soviets might be launching a nuclear attack at any time, having already detonated a hydrogen bomb in August 1953 as part of the Soviet atomic bomb project. Construction of the tunnel began in September 1954 and was completed in eight months. The Americans wanted to hear any warlike intentions being discussed by their military and were able to listen to telephone conversations for nearly a year, eventually recording roughly 90,000 communications. The Soviet authorities were informed about Operation Gold from the very beginning by their mole George Blake but decided not to "discover" the tunnel until 21 April 1956, in order to protect Blake from exposure.Some details of the project are still classified and whatever authoritative information could be found was scant, until recently. This was primarily because the then-Director of Central Intelligence (DCI), Allen Dulles had ordered "as little as possible" be "reduced to writing" when the project was authorized. In 2019, additional specifics became available.

Altglienicke (German pronunciation: [altˈɡliːnɪkə] (listen), literally Old Glienicke) is a locality (Ortsteil) of Berlin in the borought (Bezirk) of Treptow-Köpenick. Until 2001 it was part of the former borough of Treptow.

Interflug Flight 102 ended in a crash involving an Ilyushin IL 62M on 17 June 1989. The aircraft, while attempting to take off from Berlin Schönefeld Airport, East Germany, crashed into obstacles on the ground at the end of its takeoff, costing 21 lives.

Bohnsdorf (German: [ˈboːnsˌdɔʁf] (listen)) is a district in the borough Treptow-Köpenick of Berlin, Germany. It is located in the south-east of the city.

Bundesautobahn 117 (translates from German as Federal Motorway 117, short form Autobahn 117, abbreviated as BAB 117 or A 117) is an autobahn in Germany. The road that would become the A 117 was built in the 1960s as the A 113, intended as a connection from the A 10-A 13 junction in Schönefeld to the Berlin neighborhood of Adlershof. This road's path was similar to all of the A 117's present-day route, then the A 113's route south to the beginning of the A 13. Soon after reunification, a junction was built along the A 113 at Waltersdorf (present-day A 117 junction 2). In 1997, construction began in Neukölln on a new section of autobahn, which was to begin at the A 100 and connect the inner city to Adlershof and the already-existing section of the A 113. The new section was completed in 2008 and received the A 113 designation. The stub that was left, from Waltersdorf into Treptow, was renumbered A 117. During construction of the A 113 extension, a new three-way interchange had to be built at the point where the extension meets the existing roadway. The existing autobahn also had to be slightly rerouted, as the town's cemetery was isolated from the rest of its area by the road. The only way to resolve this problem and retain both the new junction and the existing junction was to combine the two junctions, although to this day they are still numbered separately. When the A 113-A 117 project was completed, the portion of the B 179 that ran into Berlin was downgraded to L 400, a fact that still has not been noted by most maps.

Berlin Schönefeld Airport (Flughafen Berlin-Schönefeld ) (formerly IATA: SXF, ICAO: EDDB, ETBS) was the secondary international airport of Berlin, the capital of Germany. It was located 18 km (11 mi) southeast of Berlin near the town of Schönefeld in the state of Brandenburg and bordered Berlin's southern boundary. It was the smaller of the two airports in Berlin, after Berlin Tegel Airport, and served as a base for easyJet and Ryanair. In 2017, the airport handled 12.9 million passengers by serving mainly European metropolitan and leisure destinations. In the same year, the travel portal eDreams ranked Berlin Schönefeld as the worst airport in the world after evaluating 65,000 airport reviews. Schönefeld Airport also was the major civil airport of East Germany (GDR) and the only airport of the former East Berlin. On 25 October 2020 the Schönefeld name and IATA code ceased to exist, marking its closure as an independent airport, with large parts of its infrastructure being incorporated into the new Berlin Brandenburg Airport (IATA: BER, ICAO: EDDB) as its Terminal 5 with its sections renamed to K, L, M and Q.

BER Airport – Terminal 5 station (German: Bahnhof Flughafen BER – Terminal 5) (formerly named Berlin Schönefeld Airport station) is a railway station in Schönefeld next to the formerly independent Berlin Schönefeld Airport, which has now been re-branded as Terminal 5 of Berlin Brandenburg Airport, just outside Berlin. The station is on the Grünauer Kreuz–Berlin Brandenburg Airport railway and is served by S-Bahn lines S9 and S45. Since October 2020 the station is no longer served by regional trains.

The Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung m. b. H. (English: Berlin Electron Storage Ring Society for Synchrotron Radiation), abbreviated BESSY, is a research establishment in the Adlershof district of Berlin. Founded on 5 March 1979, it currently operates one of Germany's 3rd generation synchrotron radiation facilities, BESSY II. Originally part of the Leibniz Association, BESSY now belongs to the Helmholtz-Zentrum Berlin (since 1 January 2009). Owing to the radiometry lab of the PTB [1], BESSY is the European calibration standard for electromagnetic radiation.BESSY supplies synchrotron light and provides support for science and industry. There are institutional long-time users, like the Max-Planck-Society, the German Federal Institute for Materials Research and Testing (BAM) and the national metrology institute of Germany (the PTB). Furthermore, research groups from other institutes or universities can apply for utilization (so called beam time) for certain projects.

The Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) is a research institute, which is a member of the Gottfried Wilhelm Leibniz Scientific Community. The institute is located in Berlin at the Wissenschafts- und Wirtschaftsstandort Adlershof (WISTA), its research activity is applied science in the fields of III-V electronics, photonics, integrated quantum technology and III-V technology

Grünau (German pronunciation: [ɡʁyːˈnaʊ̯] (listen)) is a German locality (Ortsteil) within the Berlin borough (Bezirk) of Treptow-Köpenick. Until 2001 it was part of the former borough of Köpenick.

The WISTA Science and Technology Park in Berlin-Adlershof was founded in 1991 after the dissolution of the Academy of Sciences of the German Democratic Republic at the same place. Today it covers an area of 4.2 square kilometres (1.6 sq mi) making it the largest science park in Germany.

Rundfunk der DDR (German: [ˈʁʊntfʊŋk deːɐ̯ ˌdeːdeːˈʔɛʁ], 'GDR Broadcasting'; from about 1948 to 1972 Deutscher Demokratischer Rundfunk, 'German Democratic Broadcasting') was the collective designation for radio broadcasting organized by the State Broadcasting Committee in the German Democratic Republic (GDR) until German reunification in 1990.
