Having always found contrails to be a pretty site, especially near sunset, I don't see anything unusual in the photos shown on this site. The photos look more like the effects of the wingtip vortices on the contrail twisting it into a corkscrew shape. This happens several seconds after the plane has already passed by. Just my opinion, though.

I thought a clearer indicator for the Aurora/Hypersonic aircraft with an external pulse-detonation engine would be a dotted line contrail. Engine on/Engine off in rapid succession, making a dotted line.
