That always puzzled me.The incoming B-17s also caused Lt Tyler to shrug off the Opana Point radar detection of the Japanese first wave. He told Elliot and the other guy whose name I forget that they were the expected incoming Forts.
The attack waves would have been coming from a different direction and with a more significant "blip".
I know early radar didn't have the definition or detail of modern radar systems, but something should have tossed up a few red flags with that contact.
At least the Enterprise's inbound VB-6 and VS-6 elements knew something was afoot, they just didn't expect the Japanese to be at Pearl when they arrived.
