No problem, really. But for those that are not veteran researchers and did not understand my reference, I can take a scanner or (my preference) a camera with a close-focus lense and lots of film to the US National Archives and copy all the photos of Gooney Birds I wish without paying a fee. This liberal attitude does not extend to such wonderful British institutions as the Public Record Office (PRO), Imperial War Museum (IWM) and RAF Museum (RAFM). They want a substantial fee for photo reproduction rights. As Ospreys require a lot of photos, the author of such works is basically, as the RAAF says, up a a gum tree.
