The Once-Secret Contract Between the Wrights' Heirs and the Smithsonian Institute

In 1948, the Smithsonian Institute and the Wright brothers' heirs entered into a contract. The contract was kept secret until a US Senator invoked the Freedom of Information Act to force its exposure in 1976. The contract requires the Smithsonian Institute and all its affiliates/employees to state that the Wright Brothers made the first powered, controlled, sustained flight. It thereby hinders investigation of other flights before that date. Indeed, it requires that they be denied by the Smithsonian Institute. A 1978 book by Major William J. O'Dwyer (USAF) entitled 'History by Contract' was the first to comment on the Contract. It was Major J. O'Dwyer who had enlisted the US Senator's help to expose the Contract. The following text is the display label, the stipulation:
