A week or two ago there was a story about the plane hidden away on an inner page of the Washington Post. It quoted "authorities" as saying:
1) The plane seen in Bierut was not the missing plane.
2) They didn't know where the plane was, but assumed that it had crashed or was being parted out.
In my best conspiracy theory mode, I wondered if it was a planted story since it was just a summary after a long idle period and not written by their main aviation writer.
