"Impossible" Aircraft

Some history..
NASA high speed balloon

I wouldnt be surprised in the least that the world powers would have some type of unconventional aircraft. I've had my share of ufos that are mind numbing to think about. Wether they actually succeeded or failed, I have no idea.

I did have on the rare once or twice occasion seen aircraft that made me say, you dont see that every day, albeit, they were very high up to make out anything

I recall seeing one craft literally look like a solid five tipped orange star for a few moment only see a craft of some kind with a very bright single strobe light from the bottom, an a small one at it rear. It didnt even flicker like other headlights on planes.

The other one i saw, from what I remember just had 3 or 4 strobe white/blue lights that didnt follow suit of commerical craft, all the while both didn't make a sound.

Other then that, those are the only one I can think off and this was in 2014.
