    Never ceases to amaze me the lengths man will go to fully embrace the phrase "Gotta go fast".
  • If the SR-71 was around in the 1960's, the mind boggles on what could be around now.
  • 1992, Okinawa, Japan: While playing volleyball with my fellow Marines, I noticed a contrail at high altitude. It was the classic doughnuts on a rope shape. I couldn't see the aircraft, but I could see it forming and moving. It crossed the entire view of the sky in about 20 seconds. No sound, no sonic boom after it passed from sight. Very impressive to witness.

    Airline pilot here, earlier this year I watched donuts-on-a-rope contrails being made up close by the most unexpected source. At cruising altitude just before top of descent into LAX we were passed by a 737 a thousand feet above. Both the 737’s engines were leaving contrails that were sort of rolling back on themselves, forming into rings at regular intervals. I suspect it had something to do with the mixing of hot turbine exhaust and cool bypass air forming ring vortices and the conditions were just right whether it was speed, thrust, temperature, moisture, or some other factor(s) causing it. In one way it’s disappointing they weren’t being produced by some black triangle but in another way it’s fascinating that they were formed by such a benign and common type.

    I know a lot of you wont believe me, but back in around 2012-2013, new years eve, some missile or plane flew over Ontario, Canada. It was so fast and the “shockwave” was so strong that it shook the house and made a sound as if a huge piece of ice fell from the roof. I went to school the next day and everyone at school heard it, even though we live far apart from each other. Literally everyone. It was the buzz in high school. Ive been to several air shows so i am well aware how jets sound like. Funny enough, so many people heard it in Ontario that the same morning there was a segment on CP24 stating that this was all just something related to the weather and how the cold air interacts with the atmosphere (something like that idk) blah blah. This “boom” occurred at around 9-10pm and very cloudy conditions. As i started looking into conspiracies and especially those related to flight, the second i heard about pulse based jet engines, i knew some top secret flew over the province. It would have been perfect conditions for it, low clouds, cant see a thing, slightly foggy weather, no sun, thick clouds, etc

    I grew up in Barrow Alaska on the arctic seaboard and in 91' and 92' while out skywatching we saw a few times, these pulse craft flying incredibly high covering huge distances in mere minutes. One time we watched one making a big arc in the sky with another craft cutting the arc in an apparent attempt to cut it off . We didnt see what happened as they flew out of our sight headed north east.

    Scramjets were designed in the 1930s. Material science took decades to create materials that could withstand the heat created by travel at the speeds the engines were capable of. The program trying to design a fusalage for the engines was public in the 80s.
  • For very remote airbase, RAF Macrihanish has surprisingly extremely sophisticated ground electronic equipment. Another rub chin been RAF Benbecula, also remote Scotland. Might be backup.
  • @egaroadkill8701
    Back in late 80's one doughnut on a rope contrail, with associated seismic track, drew a straight line to Johnston atoll while another one to Eniwetok. I heard others tracked similarly. I even had the displeasure to hear the "sky ripper" early in the morning in the Navada desert. I have a friend from childhood who had the life path I dreamed of being an Air Force aerospace scientist from 79 till 2010. We met at a school reunion. I asked him about what he could tell me and he replied it's beyond your imagination. I reminded him of just how advanced both our imaginations were back when we were in school, and he said that it was still beyond that. I had an uncle who was an Air Force LT. General that served in the technical field for 40 years. He pretty much said the same. He also knew about my technical knowledge and imagination. The US has been working on some seriously advanced stuff. I can see why the SR-75 is no longer with us. It's out dated and a waste of money.
  • @DFWRailVideos
    Flying a pulse-jet powered aircraft over populated areas in England, especially only forty years after WW2, is going to raise some eyebrows.
  • @jettack531
    Looks like if a sr-71 and xb-70 were combined
  • @DavidMitchell79
    In the spring/summer of 1997 I observed something appearing to be the mother craft for this flying from west to east over Grass Valley and Nevada City in California. What attracted my attention was the very "solid" looking contrails that did not dissipate as quickly as normal contrails. The plan form was similar to the SR-71 but was much larger. The forward fuselage was longer in relation to the delta wing area than that of the SR-71. There were no inlet spikes or engine nacelles in the leading edge of the wing. Having maintained the navigation systems of the SR-71 for nearly 7 years during my USAF career, I was certain this was not one of them. The aircraft was flying low and slow and over a low population area of northern California. If that was this mother ship, I suspect it must have had some form of IFE (in flight emergency) that necessitated the slow flight envelope. Around the same time frame, I would see three KC-10 tanker aircraft flying in formation over my residence at Penn Valley, CA on Thursday afternoons. About a half our later I would hear a loud growling sound going high overhead. Looking up, I could see nothing, No contrails no aircraft. The sound travelled from the south horizon to the north horizon in approximately 30-45 seconds. Yes, the government and contractors can keep aircraft projects secret for years before the public ever hears about them. The F-117 was a prime example.
  • @forbiddenera
    9:14 250 miles at Mach 15.. so like 1.3 minutes of flight time 😂
  • @keirfarnum6811
    That last little bit about the oil platform worker and “seasoned aircraft ‘observator’ [sic]” (it’s “observer”) is a reference to Chris Gibson, who witnessed a triangular craft being escorted by two F111s in the North Sea in the 80s or 90s (IIRC). Gibson was an award winning aircraft recognition expert who couldn’t identify what he saw from the oil platform he was working on.
  • @lionemessi
    I have been hearing about this plane for about 20 years. Im starting to think bigfoot flies it
  • @theeddorian
    One fact that you missed concerning the Southern California hypersonic sonic booms, is that the USGS seismograph system that detected these, was replaced by the Department of Defense, according to many sources. This new system, somehow, no longer detects, or possibly filters out sonic booms from aircraft.
  • @FluidKaos
    I have the Testors model you built some of your CGI around. Built it back in the 90s. It came with a "Rusian satellite image" of Area-51 as part of the background/instructions before such things were commonly available. It'd be great if this thing were real; but, having worked with or for the DoD for decades, and watching space things happen as an enthusiast, I'm not convinced this got past paper studies and design ideas. I'd be more than excited to find out I'm wrong though.
  • @Mr.Pie93
    I know a guy out in Arizona near Bullhead City. We did some ATV tours with him and he had a desert homestead with a bunch of very nice things such as Xboxes, PlayStations, a bathroom being Nicer than the one at my house, and much more. He is also completely off grid, in his early thirties and has lots of friends who work in the government on things like this. As we were going around the trails in the black mountains he would go on to tell me that he had this one friend who told him, as well as he somewhat witnessed himself, an aircraft that went across 6 states in five seconds. He told me all about it and how he has seen these secretive aircraft with insane speeds. And this was all before the hype of the dark star and all of that. I truly do believe without being some conspiracist that the U.S. does in fact have these hypersonic aircraft.
  • @Huxtive
    I love how the plane turns its rocket engines on and off. It's like farting countless times
