In a book by Zinn, Attack on Pearl Harbor, flaws in the execution of the attack. No coverage by the fighters, resulting in the loss of planes from the few fighters that did get airborne and of which none were shot down. No AA suppression resulting in the loss of planes and rerouting of others. Over concentration on BB's, resulting in no deliberate attacks on the CA and DD's in harbor. No control over the torpedo attack resulting in overconcentration on two. The flare problem was a result of a last minute adjustment of the plan and allowed a mistake that lead to quick response of AA which lead to problems with torpedo attacks. An example one destroyer was credited with shooting down 4 TB's. Say it was said that the flares would be launched only if there was no surprise, the torpedo planes could have launched their attacks with out flack interference. But since the DBs got their strikes in first, ships got warning allowing the quick response of ready AA. One of the biggest flaws was almost half of the torpedo's were launched at just 2 ships, another 4 or so were launched at the Utah. Six torpedo's could have been launched at each of the 4 open BB's and the rest used on the CA's in harbor. The DB's that were to hit the carriers could have been used to hit the CA's and DD's reducing flack and damaging ships that were used. Fighters should have been used to cover the airfields to prevent any fighters from taking off. Instead fighters were attacking civilian cars, civilian planes and other less important targets.
