I was taking my dog out this morning and at 5:58 am i looked up and noticed an evenly spaced ( i cannot even estimate how much distance was between each light due to the altitude ) and straight line of lights extremely high up in the sky traveling east at unbelievably high speeds. i do not know how many had passed by before i went outside but i counted 8. these were traveling much to fast to be commercial or personal aircraft. after watching these pass by, i went in and checked multiple flight tracking websites and there was only one commercial aircraft flying in an easterly direction over my area in the of southeast oklahoma at the time i witnessed these lights, no government craft were in the area according to the flight tracking websites. realistically it could have been some type of government craft i guess, but flying that high at that velocity would be amazing technology for us. if there were not multiple lights in a single file traveling at an extremely high velocity in the same direction, i would have written this off as seeing a satellite.
