I was watching air craft flying over head at about 30,000 feet in known fiight paths and all of a suden i caught a flash at about 45 deg. east. a few seconds later there was a nother flash in about the same spot. afew more seconds whent by and there was a bigger and brighter flash in that same spot. i waited a few more minutes consentraiting my eyes on that spot. and didnt see any more flashes.
