My bet is that this is not the only successful test flight that has been carried out with this aircraf; as I seem to recall that some years ago a
weather satellite picking up an almost 'Pulse-like' contrail left by something that was estimated to be travelling around 8,000mph. I would
most definetly link to two cases and call them the same aircraft.
Too cool, of course this is just the public version, God knows what they really have a this stage.
On another note, Ive seen a contrail just like that over my house, with what I described as doughnuts coming from the side, along with other weird
double helical ones.
That's pretty cool. Although I'm a believer in the look at the most advanced technology that the military has that they let us know about, such as
this, then add 50 years.
2 trillion in "lost" funds can build a lot of cool stuff.
