no actually, I've seen alot of material about the aurora. Some stuff tells that there is a sonic boom, but then there is this stuff, a video for example, that shows a small black thingy flying damn fast, but yet the dude who is recording it with the vid cam hears no sound. (ofcourse the sound would come alot later, but he never said anything about any sounds to the newspapers etc)
But of course a normal jet engine won't do. I've read that thet possible engine types would be Pulse Detonation Wave Engines, Pulsejet Engines or Advanced Ramjets.
My gues would go for Pulse Detonation Wave Engines. And if I remember correctly, that type of engine, instead of burning the fuel, makes it explode, therefore gaining a much bigger thrust, and that means higher speeds.
And that kind of engine would produce the kind of trail that ppl have seen on the sky near Area-51.
But that kinda engine would, to my understanding, produce alot of noise, so they would know that it was there.
But I gues we will never know the whole truth.
Ohh: and the video was taken near LA, so kinda points toward some aircraft operating from Area-51.
