  Pitcairn-Cierva PCA-2 Earhart lands at Grand Central Air Terminal to learn that she had been beaten by only 10 days by Johnny Miller in his PCA-2. (Stephen Pitcairn coll)

Amelia had two different accidents; the first was at Abilene TX on 6/12/31. A second PCA-2 was flown to her to continue her transcontinental journey. On 9/12/31, she dropped it in from 20 feet at Detroit. She was quoted in the New York Times as saying, "Nothing to it, it was all my fault, and I'm not injured at all. I just didn't level off soon enough." Then, "Within a few hours after the crash, Mrs Putnam set out for Saginaw in another Autogiro to fulfill an exhibition flying engagement."
