Kosmos 140
Kosmos 140 (russian: Космос 140 meaning ''Cosmos 140''), Soyuz 7K-OK No.3, was an uncrewed flight of the Soyuz spacecraft. It was the third attempted test flight of the Soyuz 7K-OK model, after orbital (Kosmos 133) and launch (List of R-7 launches (1965–1969), Soyuz 11A511) failures of the first two Soyuz spacecraft. History The follow-up to Kosmos 133 (Soyuz 7K-OK No.2), 28 November 1966, was planned for 14 December 1966 (Soyuz 7K-OK No.1) but ended disastrously. At liftoff, the Blok A core stage of the 11A57 booster ignited, but not the strap-ons. A shutdown command was immediately sent and pad crews began to move the service towers back in place and drain the propellants. This task was completed for the core stage and strap-ons, and then about 27 minutes after the attempted launch, the launch escape system (LES) suddenly fired. Its exhaust caused the Blok I third stage propellant tanks to overheat and explode, killing one person on the ground and damaging the Soyuz ...

Flight Test
Flight testing is a branch of aeronautical engineering that develops specialist equipment required for testing aircraft behaviour and systems. Instrumentation systems are developed using proprietary transducers and data acquisition systems. Data is sampled during the flight of an aircraft, or Atmosphere of Earth, atmospheric testing of launch vehicles and Reusable launch vehicle, reusable spacecraft. This data is validated for accuracy and analyzed before being passed to specialist engineering groups for further analysis to Verification and validation, validate the design of the vehicle. The flight test phase accomplishes two major tasks: 1) finding and fixing any Aeronautics, design problems and then 2) verification and validation, verifying and documenting the vehicle capabilities for government certification or customer acceptance. The flight test phase can range from the test of a single new system for an existing vehicle to the complete development and certification of a ...
