Sonic Boom followed by 3 UFOsAt approximately 10:55pm on 5/10/10 me, my girlfriend, and my dog all heard a very loud boom. Our house completely shook. After investigating my house for a couple of minutes we heard some jets that sounded like they were flying extremely low. Me and my girlfriend went outside to see if we could find out what was going on. After a couple of minutes outside, at approximately 11:00pm my girlfriend noticed a glowing light hovering in the sky. After about 5 seconds it faded out. About another 10 seconds later three lights appeared in the same area. They were all staying still. They were there for no more than 5 seconds, and disappeared. A minute or two later one single light appeared in the same area for no more than 5 seconds. We are located on the North Side of Havre, the lights appeared South East of our location.I assume the initial loud noise was a sonic boom created by the jets.
