There appears to be an unknown aircraft type that is flying over the United States. This triangular craft was photographed over Wichita Kansas doing broad S-turn maneuver. There are a number of possibilities. The contrail is tight and not unlike the B-2, but the B-2 cools it's exhaust so less likely to produce contrails. The contrail has knots in it which would be somewhat reminiscent of images taken near Las Vegas which have been seen and heard with an odd rumbling sound. While speculation that the Vegas sighting was tied to the Aurora, this does not look like what the Aurora was thought to look like. It might however be a launcher platform of some type and it might have been doing the s-turn to slow down before returning to Area-51 after launching an orbital plane of some sort, and perhaps uses the same general type of engine as the Aurora.
