The story of Japanese capture and killing and disposing of the plane without a trace, means that hundreds of soldiers and sailors, not to mention those in charge back in Japan that would have made such a large decision, would have had to keep it secret all these 82 years and other than the testimony of a few natives on Saipan, no contradictory evidence of their guilt has ever come forward, not even rumors. Now is that possible, is it likely? Japan was a closed society very militaristic and dictatorial so maybe it could be kept under wraps all that time. During the war when Japan was beginning to lose and being driven back from the islands, the pilots going home on leave were told not to talk about the battles and certainly not about their losses. I don't think they had independent media people out on the battlefield like the Allies did.
