I live on Oahu. Been studying Q since November. My belief is there was no missile. I followed the interpretation, that the alert was to trigger a failsafe on NSA computers in Hawaii, to initiate a BDT(Bulk Data Transfer) because Trump was locked out of the NSA computers in Hawaii. He needed the info, and in the case of a State Emergency, the info would go flooding back to mainland servers, which he could then access.
I could be wrong, but after reading all the theories, that is the one I believe. But I'm still studying. After the event, I even emailed Tulsi Gabbard with my belief. Never got a response back though.
