Dog-leg (stairs) A dog-leg is a configuration of stairs between two floors of a building, often a domestic building, in which a flight of stairs ascends to a quarter-landing before turning at a right angle and continuing upwards. [1] The flights do not have to be equal, and frequently are not. Structurally, the flights of a dog-leg stair are ...
The sites included Naval Air Station Bermuda, Lajes Air Base in Terceira island, Azores, Portugal, Zaragoza Air Base in Spain, Morón Air Base in Spain, and Istres Air Base in France. [11] All sites have runways of sufficient length to support the landing of a Space Shuttle, and included personnel from NASA as well as equipment to aid a space ...
It was used for the first docking to a space station in the history of space flight, with the Soyuz 10 and Soyuz 11 missions that docked to the Soviet space station Salyut 1 in 1971. [1] [15] The docking system was upgraded in the mid-1980s to allow the docking of 20 ton modules to the Mir space station. [16]

The runway was first used to land a Space Shuttle on February 11, 1984, when Challenger's STS-41-B mission returned to Earth. This also marked the first landing of a spacecraft at its launch site.
t. e. SpaceX has privately funded the development of orbital launch systems that can be reused many times, similar to the reusability of aircraft. SpaceX has developed technologies over the last decade to facilitate full and rapid reuse of space launch vehicles. The project's long-term objectives include returning a launch vehicle first stage ...
Microwave landing system. The microwave landing system ( MLS) is an all-weather, precision radio guidance system intended to be installed at large airports to assist aircraft in landing, including 'blind landings'. MLS enables an approaching aircraft to determine when it is aligned with the destination runway and on the correct glidepath for a ...
