I was watching an old movie titled The Beginning or the End, about the dropping of the atomic bombs in 1945, and it had very nice actual footage and studio-made segments on the atomic bombs dropped by the 509th Composite Group. Very nice classic B-29 footage! It reminded me that all of the Silverplate B-29's were Martin-built at their Omaha, NE plant, and that Col. Paul Tibbets picked his mount personally when he visited to check on the progress of the modifications to the aircraft. I have attached a link to specs, photos, and history of the Silverplate B-29's.The 74th anniversary of the missions just passed, August 6 and August 9, 1945. Amazing that both of the B-29's that dropped atomic bombs were preserved and that they were both flown to their respective museums from storage. I hope the link will be of interest. (You could tell the studio-created footage, as the props on the B-29's they used to represent Enola Gay and The Great Artiste were Hamilton Standard instead of the correct Curtiss-Electric reversible props fitted to the Silverplate B-29's.)
