I love that they are try to sell a model of the plane in the second link, suggesting it is 95% accurate, sure it is. I think I still have an f-19 model from when I was a kid(should be f-117), aside from color it couldn't be any more wrong.

When asked by an audience member about the Aurora or whatever it's called, he said that he had no direct knowledge of it, but he heard an aircraft land at Edwards, at night, and that it sounded unlike any other engine he had ever heard. For someone that was a test pilot from just after WWII on through the X15, SR71, etc., to say that gives one something to think about. Also, does "external combustion" pulse jet mean anything to you guys? That's about all I've been able to piece together.

The way the idea was explained to me:

ever squeeze a watermelon or pumpkin seed to squirt it across the room? Pressure from your fingers above and below the seed provides propulsion forces.

shape the fuselage like that seed, and dump raw fuel onto the external surface of the aircraft. It will ignite from the heat of the aircraft skin. The explosions are contained between the fuselage wall and the shock wave. Pressure from the explosions will push the aircraft forward.

This has to be done in pulses; it cannot be continuous, because the explosions destroy the shock wave, and it needs to re-form before you have a "combustion chamber"
