    Dear Earthling, Chapel Tibet. We gave up on Electro Magnetics centuries ago.

    Unviable ?? Try non-viable and how does the engine running temperature threaten the structural integrity of the aircraft when its out on an under slung pod ?

    Mach 5 in terrestrial airspace? At Mach 2 Concord use to expand due to the heat generally. I cannot remember by how much but it wasn't small. So how are they going to overcome the frictional heat at Mach 5 in terrestrial conditions?

    4 hours Europe to Oz? Add airport check ins , parking issues, sitting next to smellies or idiots that keep bashing the back of your seat. Nah , I'm waiting for the Transporter from Star Trek.

    "Electro-gravitic propulsion" was developed in 1929. So, how far behind the military industrial banking complex curved are you?

    The reason I believe hypersonic planes are not practical is heat. It would make much more sense to go up another 200,000 feet to be nearly free of the friction from air and would additional shorten the flight times burning less fuel.

    "High Octane kerosene" for a jet engine. That's a joke, right?
    hopefully the rest of the video is more knowledgeable.

    The SABRE engine is in fact a liquid air rocket which was once called LACE for Liquid Air Cooled Engine which was once proposed for NASA's single stage to orbit concept. The issue with cryogenic cooling of surrounding atmospheric air is that ice clogs it up, SABRE plans to address that by using the supersonic intake to create a strong vortex so that dry air tends to be on the outside of the vortex while humid air tends towards the center hence keeping the humidity away from the cryogenic cooling radiators, basically an induced centrifuge. Normally, I would give them respect for at least trying to be creative but then they go off to say their engine can operate from a standing start through takeoff and then to hypersonic speeds when their entire premise requires supersonic to hypersonic speeds to begin with. Any such start from a standing start implies a hybrid multimode operation where it can operate as a conventional jet or rocket at the slower speeds without the cryogenic cooled liquid air. The promotion for a lot of these concepts is what loses my respect for them as the people doing the promoting have no idea what they are talking about and thoroughly misrepresents the proposals.

    "EU Funded Project"…..Tax dollars helping private business. How quaint. And they complain about Boeing selling planes to the US military which is somehow a "subsidy".

    All very well being able to travel from London to Australia in 4 1/2 hours, but you still spend hours in the airport before you get on the aircraft and get off. That's the part that they need to work on!

    Never Happen. Yes, we can do it but we can't afford to do it. No airline company can afford to pay for the fuel to fly that fast. Any Air Force 'Jet Ace' will tell you … ~Resistance Through Air Squares As Speed Doubles.~
    Top speeds for jet air travel is a hair under 500 knots. Can't fool Mothe Nature.
    Air entering the SR-71 needed to be slowed down by screwing an inlet cone into the air inlet of the Pratt-Witney J-86 engines. Without the cone, the air entering the engine at speed is the consistency of molasses. https://www.youtube.com/watch?v=m5qZZ3X44Go.

    WHAT A BEAUTIFUL BIRD. MAC 5 ! Wow, for anybody who's been in TESLA technology and running it, it's so powerfull acceleration that you need very solid seats. No doubt in my mind, that's the futur of aeronotic, combined with crusing solars. Lot more efficient than carbon fuel and no pollution. Gerry

    Humans of Earth seem to still be buying their idea of "jet" engines whilst everyone else around ye olde galaxy is running electro-magnetics. C'mon, folks, catch up.

    It runs on compressed air would not be surprised if they split the air molecules during compression , there is no way they have all that fuel in the wings , and all pumped in there in less than 7 minutes , they apparently fill the wings with fuel that would fill olympic sized swimming pool, s , so now the jig is up , so they have too cover their ass,s with this BS , they have to keep air travel at high ticket cost as they pull the wool over peoples eyes . I cannot remember when they moved the engine forward from mid wing , anyone ? I remember when all commercial engines where under wing not in front .

    Engine heat is not the only worry at Mach 5. Mach 5 is around 3,835mph, (depending on your altitude), and when the SR71 got up to around 2100mph, its skin got up to around 600 degrees F. That is why it was made of Titanium. Somehow, I don't think a Titanium airliner carrying 300 people from the UK to Australia at close to 4,000mph would ever be a money maker. Didn't the failed Concord teach the British anything?

    Speed is one thing but aircraft structures are another. Mach five will take a hell of a lot of titanium and who has large deposits of this stuff? Russia, of course. Maybe they’ll be able to make a high temp plastic out of carbon. Who knows?

    Interesting concept…even if it works as advertised, would be limited to over-water routes due to sonic 'booms', like Concord.
