The records include 27 tapes spanning about 30 hours, and 570 pages of transcripts. Museum officials say the existence of those tapes and transcripts had never before been confirmed, adding that they are important as they depict in detail the situation inside the bomber and the psychological state of the crew. Tape recordings of testimonies by Enola Gay pilot Paul Tibbets and others are shown at the Hiroshima Peace Memorial Museum in Hiroshima's Naka Ward, on July 20, 2018.
