Two rare, historic and rarely-seen documents relating to the history of aviation and the exploration of spare are on display at Seattle’s Museum of Flight through the end of May.

The first document is the original contract between Wilbur and Orville Wright and their creation, the Wright Company, in 1909. In the document, the brothers agree to transfer and assign to the Wright Company two U.S. patents that describe their successful flying machine.

The other document is the 1969 Apollo 11 Command Service Module Maneuver Card, which has Neil Armstrong’s and Buzz Aldrin’s most extensive flight notes from the first visit to the Moon.

Cool, right? Both papers are part of the museum’s permanent collection, but are rarely shown because of their value and fragility.
