I was living on that island at the time, the military base is at the northwest part of the island, the military base did not react to "any possible missile launch", nothing (if it was not them, if it was unknown or even suspected to be you would think they would of went straight to red alert but, nope nothing.. The ATC on the base alert if even a small plane enters the airspace without making contact to the tower.. as it was all over the news there and called "it was a mystery light" not "a missile launch". Did it even happen? IDK.
