Chrome orbs size of a basket ball moving from 0mph to speed of ?at about 10 thousand feet up.On Thursday 6/6/02 at 10:45 in the morning i was working when a coworker was looking skyward i looked up and say 2 balls about the size of a basketball.they were chrome in color.as we talked i noticed that one seemed to be moving up.they seemed to be as high as you might see a passenger jet flying overhead.the secound one was dropping toward us and moving from east to west at first i thought about weather ballons but the closer it got the bottom seemed to have a transparent bottom to it.by this time they were getting further apart from each other the higher one kept moving up it was out of sight in 3 min.the secound kept getting closer it was now moving east to west faster than dropping at about 4 to 5 thousand feet it just seem to slow and stop.we are next to a small airport.it seemed to stay just outside the landing paterns of thr airport.after 5min of watching this (orb) it excellarated so fast to the west if you would have blink you would have missed it.not a cloud in the sky that morning no wind at ground level (i have perfect vison)
