a friend and I were talking outside for about 10 minutes when I said look at that up in the sky what I thought I was seeing was the iss or sattalite except its brightness was irregular compared to most moving lights I have seen. I watched as it crossed from west to east above the clouds but unlike a plane or sattalite it never dropped below the horizon instead it stayed a course straight into space judging by the angle it approached and left. I followed it for the entire duration and then some. as it left away from me it went from white to a dim glowing orange at its rear once it left sight about 20 seconds later there was two flashed of lights like lightning seen from a great distance within a minute there were two rumbles of thunder in sequence with the lightning flashes. my theory is they used the explosions to ride the shock waves in space. I am a person of reason I never experienced anything like this and prior to this I thought I seen a ufo but the sighting I am reporting today exhibited intelligence it was an unearthly object propelled into space the creations of man cannot complete such actions.
