Within 30-60 minutes time i observed 5-6 separate flying objects, each with two paired, white, non-blinking lights, closely set lights. they were noted at different times, several minutes apart, in random locations, headed in different directions, like non-coordinated fashion. i could not make out any body shape on any craft, the sky was dark, in city with light pollution. the craft must have been very similar since the lights (two) were set in identical pattern on each craft. the craft each flew at a moderate speed, even, straight course. i could follow each with and without use of binoculars, and track easily for 15 - 20+ seconds. no sound. seemed to be at commercial jet cruising altitude, or more?? i noticed an airplane (with flashing lights) several minutes before i saw the first ufo and a second airplane more than 15 minutes after the last ufo noted.
