Got a feeling we have seen the last military fighter/bombers we will ever see. Except on the ground. Something just flew over the house, right over the top, clear sky, sunlight. It was loud, but the only sound came from the exhaust that was cranked to the max. The sound was also highly variable, not like the usual 747s, etc that go over. The plane was fast, too, and when they cut back the thrust the sound of the exhaust was gone. No engine sound at all.
Oh, and invisible.
