After setting off some fireworks i saw an orangish red light in the sky above my yard. i pointed it out to my girlfriend and friend. it was about as high as a jet would fly (hard to estimate). it was not a spark from the fireworks. it flew in a straight path faster than a plane and didn't change elevation. we saw it for about 5 seconds then it disappeared. there was no cloud cover. it had no blinking lights. the three of us tried to figure out what it was but had no conclusion.
