What does this number measure?
The measurement concerns the orbiter alone, without the external tank or boosters. Displayed dimension: orbiter length.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
Source and limitations
Catalogue value to check against the source; not individually audited.
Space Shuttle orbiter alone, longitudinal profile.
First orbital flight: 1981. Proposed historical date; an existing documentary source is linked but was not consulted for this date in this session. Do not interpret this reference as the manufacturing date of the illustrated specimen. First orbital flight of the American Space Shuttle (Columbia, STS-1); Enterprise's atmospheric tests in 1977 came earlier.
