Mesta Press East Side
The ''Mesta'' () was a powerful association protecting livestock owners and their animals in the Crown of Castile that was incorporated in the 13th century and was dissolved in 1836. Although best known for its organisation of the annual migration of transhumant sheep, particularly those of the Merino breed, the flocks and herds of all species of livestock in Castile and their owners were under the oversight of the Mesta, including both the transhumant and the sedentary ones. The transhumant sheep were generally owned in Old Castile and León, where they had their summer pastures, and they migrated to and from winter pastures of Extremadura and Andalusia according to the season. The royal protection for the Mesta's flocks and herds was signified by the term ''Cabaña Real'' ( that applied to these protected animals. The kings of Castile conceded many other privileges to the Mesta. The ''cañadas'' (traditional rights-of-way for sheep or sheep-walks) are legally protected in pe ...

Heavy Press Program
The Heavy Press Program was a Cold War-era program of the United States Air Force to build the largest forging presses and extrusion presses in the world. These machines greatly enhanced the US defense industry's capacity to forge large complex components out of light alloys, such as magnesium and aluminum. The program began in 1950 and concluded in 1957 after construction of four forging presses and six extruders, at an overall cost of $279 million. Eight of them are still in operation today, manufacturing structural parts for military and commercial aircraft. They still hold the records for size in North America, though they have since been surpassed by presses in Japan, France, Russia and China. The program produced ten machines, listed below. Background The Heavy Press Program was motivated by experiences from World War II. Nazi Germany held the largest heavy die forging presses during the war, and translated this advantage into high performance jet fighters. Because of the s ...
