I was in my front yard looking at stars and saw what i originally thought was a plane with its headlight on. however it did not have the flashing red/blue lights that planes/helicopters have. within 30 seconds of watching the light, the light dimmed and flashed completely out. before it extinguished, it was dimmed momentarily and i believe the belly of the craft had a matte finish and was dark gray or black. i could not see the craft moving after the light was extinguished. i feel that it might have been oval shaped but can't be sure. as i ran into the house (out of fear and excitement), we started (my husband and our friend) to hear what sounded like thrusts and then explosions very far off somewhere. they sounded timed (3 booms and approx. 10 seconds later, 3 more thrust/booms) for a total of about 6 rounds. this went on for about 5 minutes.
