First of all, congratulations with the catch!

Contrails can form above 40.000 ft, but itís rare.

Iím surprised you could hear the aircraft; if we assume it flew at 70.000 ft and you were still able to hear it, that means itís not particularly stealthy as that implies it has a very loud acoustic signature. This is especially strange as I would expect the RQ-180 to be relatively silent with itís hidden, inboard engines to begin with.

So, the fact that it produces contrails and produces audible noise suggests that itís flying at a relatively low altitude; certainly not at 70.000 ft.

As so often this raises only more questions, but Iím sure weíll find out more soon!
