An original Wright brothers patent application that had been missing since 1980 was found in Kansas last month, in a limestone cave used to store records, the Washington Post reported this week. The packet of papers was supposed to have been kept in a vault at the National Archives in Washington. But when officials looked for it in 2000, to display at a special event, it was missing. Curators have been looking for it ever since.
