Buran Programme - Status

Status

As well as the five production Burans, there were eight test vehicles. These were used for static testing or atmospheric trials, and some were merely mock-ups for testing of electrical fittings, crew procedures, etc.

Famous quotes containing the word status:

    The censorship method ... is that of handing the job over to some frail and erring mortal man, and making him omnipotent on the assumption that his official status will make him infallible and omniscient.
    George Bernard Shaw (1856–1950)

    [In early adolescence] she becomes acutely aware of herself as a being perceived by others, judged by others, though she herself is the harshest judge, quick to list her physical flaws, quick to undervalue and under-rate herself not only in terms of physical appearance but across a wide range of talents, capacities and even social status, whereas boys of the same age will cite their abilities, their talents and their social status pretty accurately.
    Terri Apter (20th century)

    What is clear is that Christianity directed increased attention to childhood. For the first time in history it seemed important to decide what the moral status of children was. In the midst of this sometimes excessive concern, a new sympathy for children was promoted. Sometimes this meant criticizing adults. . . . So far as parents were put on the defensive in this way, the beginning of the Christian era marks a revolution in the child’s status.
    C. John Sommerville (20th century)
