Recent weird meteors:Secret Pulse Detonation Wave aircraft or spaceplanes?

(note:I changed the title of this thread because the old one was confusing... the Pulse engine stuff is a few posts down)

In the last two months there have been several spectacular meteor sightings. Washington state, Australia, and now Texas have each had sightings of amazing meteors that have lit up the night sky... but for which no impact sights have been found (though these meteors may have been as large as a desk in some cases). Now... when video has been provided of the meteors, they don't appear to be breaking apart on the way down... at least not noticeably.

So... what are the possibilities that these could be returning US spacecraft? It sounds silly until you think of how a night time reentry would look for a large spacecraft.

Though this is an older proposal, something like this could be responsible... and american flying saucer that would reenter the atmosphere like the space shuttle:

And there's also this project:
The Black Horse orbital spaceplane, proposed by the USAF a decade ago

So... does anyone else think that such black spacecraft could be the cause for these mystery meteors. keep in mind that NORAD has informed FEMA that more such lights will be coming soon... Is such a comment a cover for an extended, multiple launcxh summertime mission?

According to the article the craft requires a place to land. They mentioned using a dry lake bed as a landing strip. If you could track were this vechicle came to rest than it may be what you are theorizing.

They just reported a new meteor yesterday...

Apparently, many people who spotted the "ball of fire", thought it looked like a plane, not a meteor. The National Weather Service (NWS), told everyone who called in that it was a "large meteor"

This might of been the case a few decades ago but these days I dout their craft come barreling in the way the space shuttle does.

What type of propulsion would result in a vehicle that appeared to 'glow' and pulse streams of exhaust..

Well, it turns out that an aircraft flying with a Pulse Wave Detonation Engine might leave a visual trail like that of these weird meteors (note the Texas police video):

"PWDE is an acronym that stands for Pulse Wave Detonation Engine. In a Pulse Wave Detonation Engine, liquid methane or liquid hydrogen is ejected onto the fuselage, where the fuel mist is ignited, possibly by surface heating. The Pulse Detonation Engine works by creating a liquid hydrogen detonation inside a specially designed chamber when the aircraft is traveling beyond the speed of sound. When traveling at such speeds, A thrust wall (the aircraft is traveling so fast that molecules in the air are rapidly pushed aside near the nose of the aircraft, which in essence becomes a wall; like a sound barrier) is created in front of the aircraft. When the detonation takes place, the airplane's thrust wall is pushed forward. This all is repeated to propel the aircraft. This also produces the "donuts on a rope" contrail (above). Some people think this method is very strange because when you are traveling at speeds of Mach 5-8 extensive heating is a problem, so the last thing you would want to do is detonate an explosion outside the airplane and heat it up more."

So, could we be seeing an increase in flights involving aircarft with pulse detonation engines?

The link says that they would presume the operating range to be 100-200 hertz, as opposed to the 50-60 reported by witnesses. Yet donuts on a rope contrails, by the distancing of their donuts, project a speed 4 times higher than expected at 200 hertz. Isn't the logical conclusion that the craft really is operating at 50 hertz? It looks like somebody on this website just failed to consider the obvious. I don't see what's "hard to reconcile".
As for 1 hertz... has anyone considered that the craft was slowing down, or experiencing a malfunction? 1 dimensional thinking

But a technical analysis of pulse detonation engines suggests that engines operating at the thrust levels associated with military aircraft would operate a between 100 and 200 Hertz (pulses per second). While doppler shifting may reconcile this value with the reported 50-60 Hertz pulsation, it is more difficult to reconcile this with the reports of a 1 Hertz pulsation.

It is also difficult to reconcile a pulse rate of 100-200 Hertz with the observed donut-on-a-rope contrails. The association of these contrails with a pulse detonation engine would seem to be predicated on the observation that each "donut" is a product of a single pulse detonation. Based on published photographs, the "donuts" appear to be approximately 100 meters apart. Assuming a detonation pulse rate of 100 Hertz, this would imply a velocity of 10 kilometers per second, or 36,000 kilometers per hour (roughly Mach 36), one- and-one-half times orbital velocity. While it is asserted that the Exotic Propulsion Aircraft is a high-speed vehicle, this is at least four times faster than the speeds normally associated with this aircraft.

I live in Philadelphia and I was watching the news on Thursday or Wednesday and weather man showed a video of this fire ball leaving no trail coming down and he said it was a meteor but like someone said there was not landing mark found now there aren't any AF bases near where I live except a small one so I don't know what that was.
