How a Pearl Harbor third wave could have mined the channel

Mine-laying aircraft could hide their work amid the confusion of a bombing attack and turn later ship movements into a second hazard.

Question

Could Japanese aircraft have dropped mines in Pearl Harbor and its channel during the attack?

Short answer

Potentially, especially in a third wave, because mine drops could be concealed within the confusion of the bombing and threaten later ship movements.

Notes

Mine-laying is most plausible as part of the often-discussed third wave at Pearl Harbor. Aircraft dropping mines during a general bombing attack could exploit defenders' expectation that every falling object was another bomb. The danger might not become clear until damaged or surviving ships began to move through the harbour channel. One visible form of attack could therefore conceal a different weapon whose effects appeared later.
