saw two craft (1) moving E to W and (1) moving N to S then back and a flashbulb

Did Impromptu sky watch, 8:15p-8:35p, (3) contacts
1. Very solid blue object, with one bright white flashing light, about 3x brighter than the brightest star in my viewing area. Flashes were about 1 second frequency. Moving faster than commercial jet from E to W, took only about 15 seconds to travel the full width of sky. no sound.
2. White flashbulb W by slightly south. At ~30-35 degrees. About as bright as the brighter stars in the area. (not unusual for CE5)
3. Very fast craft moving from N to S at apparently high altitude. Only saw red lights flashing rapidly, about 4-5x per second (unusual frequency) I spotted it from N just over my right shoulder and followed it south out of sight, a few seconds later I saw what appeared to be the same craft coming back from S to the N along the same path at the same speed. too high to hear any sound.
