Aboard the USS Fall River (CA-131), Bikini Atoll, 25 June 1946 – Scuttlebutt was that all went well on Queen Day, the code name for the 24 June rehearsal for Test Able on 1 July.
Commander M.E. Dennett, USN, issued these instructions to all hands: (1) Face away from Bikini, (2) Sit on Deck, (3) Close eyes tightly, (4) Cover eyes with bended arm against the face. (5) When the order “Carry on” is announced, all hands may safely observe the beautiful display of colors in the incandescent column of cloud and the gigantic clouds, which follow the explosion.
