The Ryugyong Hotel in North Korea's capital, Pyongyang, is an uncompleted hotel. Construction started in 1987 and was halted several times. Most prominently during the colapse of the Soviet Union.

The hotel existed largely in a rough construction state until 2008. From then, a Egyptian construction company, Orascom, re-started construction on the exterior part of the building. By 2011 they had completed the exterior part of the building.

Up until now, only the exterior part of the building is completed. The interior part is largely empty and no works have commenced on the interior part. In recent years, a large LED panel was fitted to one of the sides of the building.

The building is up until now never used as a hotel. Unkown is why the Egyptian construction company never finished the interior.

Did you know a 747 could carry an additional engine? The 5th engine is not working: it is carried as cargo underneath the wing to transport it from one location to another. This special way of carrying the engines is mainly used to transport an engine to an already broken down aircraft at a non-base airport. The second 747 can fly in a new engine, after which engineers can replace the engine on the broken down 747. The broken engine can be carried back in the same way to the home base airport.

Due to the drag, the performance of the aircraft is quite heavy impacted. Crews must plan additional fuel stops to account for the added fuel burn.

See for more information and a very nice description of this process this blog from Flightradar24.

The Zwentendorf Nuclear Power Plant was built in Zwentendorf, Austria. It has never entered service because in a referendum on the 5th of November 1978, a narrow majority of 50.47% voted against the start-up.

The plant was completely finished by the time of the referendum, but has never been used for electricity production. After the referendum, some parts were taken out, but in large the facility is still complete. It has been since used as a training center, a movie and photography shooting scene and location for other events.

In total the project costed €1.4 billion.

A United Boeing 767-300, registration N641UA performing flight UA-702 from Newark,NJ to Houston Intercontinental,TX (USA), landed on Houston's runway 26L at 10:34L (15:34Z) but touched down hard. The aircraft rolled out without further incident and taxied to the apron. There were no injuries.
