Missle type object, brilliant white straight light shot up into atmosphere at approximately 19:40pmApproximately 7:50pm saw what appeared to be a missile shoot straight up into the sky at high altitude towards Lahaina. Not certain if this could be from Barking Sands on Kauai. Was perhaps 3 miles high when ignited and climbed to approximately 4 miles, went out for a second, reappeared and then out....total time of climb approximately 1 minute. Left a vapor trail which lingered for approximately 10-14 minutes which was a swirl pattern. Lovely and eerie to behold.((NUFORC Note: Probable launch of an "Aegis" anti-missile rocket at 19:35 hrs.. PD))
