"There is always a 'flash' as they enter, in rotation, and in short order they disperse in a great speed, out-flying the Air Asia aircraft.  My twelve year old daughter, Jessica, was successful in taking nine photographs of a fleet as they appeared out of the blue sky...in a flash.  25 February 2011,  As it appeared these ships of rotating 'lights' did appear  as a group, but then separated into individual vehicles or lights and sped off.  One newly entered group, materialized and immediately flew over the Air Asia aircraft as Jessica was lucky to capture in a last second chance!"
