Not the northern lights.
The replacement for the SR-71.
Three times in the last few months I have heard an unusual sounding jet engine - what I believe is a pulse jet.
Last Friday before noon I saw an unusual condensation trail - that had evenly spaced nodes perpendicular from the main trail. It overlaid 4 conventional contrails and appeared above them. The path was from east southeast to west northwest.
Only one aircraft I know of is thought to use a pulsejet engine - the so-called Aurora spy plane.
Now I know that when the SR71 was still classified - it only flew nightime missions. So it is likely the Aurora would do the same.
From the direction I observed the contrail - and assuming they were landing where it was still nighttime - it would put it based either at Elmendorf AFB Alaska (where I firstbsaw a SR71) or Eielson AFB Alaska - which had the second longest runway in the world.
Any thoughts?
