Yes, it was very close, and luck and/or divine intervention swung a dicey situation our way. That in no way is meant to detract from the bravery and audaciousness of our officers and pilots and enlisted men. Our losses among torpedo planes were staggering, but as luck (fate) would have it, they drew off the Japanese fighter cover and made it possible for the dive bombers to come in more or less unchallenged. Catching Nagumo’s carriers in between recovering planes from bombing Midway and re-arming for the strike against Spruance was fortuitous almost beyond belief. And Nimitz going after the Hiryu after he had clobbered the first three Japanese carriers showed a tenaciousness and willingness to take risks to deliver a knockout blow, which he did, at least as far as the Midway operation was concerned.
As Rush might say: "talent & courage on loan from God'd"
