In our city, at one <censored> factory, in the reconstruction times, an Aglician machine broke up. The times were scarce, so a drawing of the detail scaled from the documentation was issued to the local carrier. The tower was of the sixth grade, that's why he was sober - he made the detail quickly and accurately... only when they started to install, a confusion emerged - the detail "a little" did not get up. The engineer, who calculated the drawing, was firmly convinced from the student board that the inch was equal to 2.5 (also Simplified), rather than 2.54.
