Do you think we (or more likely, the very rich) will be flying these by 2030?
Shout out Russia 🇷🇺 Z
All this at the cost of environment…
No major research in the field of saving environment and climate change
what is the percentage of possibility of surving if the accident occurred?
hoping we’ll be able to travel Hypersonic commercial by 2035…🌍🌎🌏⌛️🚀🛫
Lol. People might as well go to a venture capitalist with a paper airplane and ask for $10 million in funding. It’s more real than all this vaporware.
I m good with an economy seat in Boeing or airbus
Landing them is usually the issue
Also, hypersonic isn’t a necessary term
Still too long
I think 2030 is very likely, if they have the same work ethic as Elon musk.
Yippie… lets fly a bunch of rich A holes faster to no where and pollute the planet some more very important we don’t have any more pressing problems
6:19 one of the many EPIC failures of cost efficiency, safety and comfort issues of passenger flying concept. A winged crafts, taking off verticly, using rocket canister, heading zenith to the sky 🤦♂️. The wings grant lift in thick air and potent gravity mass altitude range! So after doing a vtol/runway, than you attempt reaching cruise path ascending at near stratosphere level, or at SR volocity start, to the low mesosphere range.
Everything BELOW the Stratosphere line, is friendly to wing form crafts, everything ABOVE it, is friendly to a ramjet/rocket thrust canister engines. This is fundemental requirements in making the most cost, safety and comfort Oribitline ( like an airliner term) in becoming an ssRtol or ssRtol THAN sstoVl sequal craft.( R as Runway ).
I’m in no hurry.
Jesus. astronauts and fighter pilots train for years to be able to handle that kind of acceleration: the promise sounds interesting but how are regular people not gonna be sick or pass out from the acceleration?
B.S. More Musk-like scamming. No super-sonic booms will ever be allowed over the USA.
They look so beautiful 😍
Hype & Animation, nothing is real.
I think mach 5 is slow speed for this plan.
A lot of talk more action is needed
I’d settle for some leg and elbow room. They want to charge me for luggage, seat priority, boarding priority, fast tsa access, snacks, drinks, movies — I’d pay to be on a flight with no toddlers or babies but the just thing would be for them to pay extra to cover everyone else’s suffering or just say you get to fly with a whole plane full of parent’s who don’t stop their children because “what can you do?”
Errrr 7000mph is almost 2 miles per second, not 1 buddy…
LtGen Steven Quast has said publicly that the Air Force has completed tech to fly anywhere on the planet in under 1 hr.
Waiting for proper leadership to release it.
I’ve been hearing this for 20 years ago, even before the Concord was discontinued. It will never happen.
Give us supersonic first, don’t rush things…
Obviously not for us gas guzzlers right. What a joke as they claim go green
Imagine hitting turbulence at Mach 9…
Chinese hypersonic is vaporware. too expensive requires 2 rockets?
They should all be heavily investing in Teleportation instead.
The concorde was discontinued but not man’s quest for supersonic air travel.
HEY! I’m still waiting for my “Self-flying airplane in every garage” future that Popular Mechanics and Popular Science were promising me back in the 1950s and 60s!! Hellooooo?! Still waiting l.… 🤣 (Nice coverage of ‘where we’re at’ and what’s being promised … more vapourware expected from this old cynic. ;-))
Now thats how you get to work.
This is still primitive technology, I’m waiting for a call asking me to assist, All of these designs treat the heat as a negative, Instead of utilising it to generate propulsion
well USA now is saying they go to space first cause we can’t have Russia doing that wonder why they don’t stop using all inventions other Russians made hmm 🤔
Maverick loves Dark Horse
I believe that if the Soviet union was still around, we would have already done a lot more. Something about the cold war that inspired scientists to think out of the box and outcompete the other side.
Excellent stuff bro

This is way more practical than tying people to ICBMs.
Let’s get away from rocket engines and concentrate more on bronn flying saucers and how they are able to Be propelled at invisible steeds with no noise
In 1975 myself and a handful of others witness a UFO one block away 1 block away broad daylight not a cloud in the sky without a sky without a sound movedIn 1975 myself and a handful of others witness a UFO one block away 1 block away broad daylight not a cloud in the sky without a sky without a sound moved 3 to 4 blocks in less than the blink of an eye with no sound it was sound and then left again and totally disappeared in front of our eyes that is the gospel gospel when we can achieve that we will have reached the future
Hermeus will not work.
Any of us can say that we hope to do something by 2029.. I HOPE to achieve flying to the moon on a winged unicorn. It doesn’t mean I will do it.
All of these concepts, are just that. Concepts. Just generating funds for research. Presenting date makes people more excited but it doesn’t actually bare fruit.
The only 2 times something was achieved within a projected timeframe, it took a nations treasury, and some of the world’s most important scientists.
The other time, it took billions upon billions of dollars, and scientific professors from all around the world working flat out for 4 years.
Don’t watch any of these videos and kid yourself. They are nice dreams, but that’s all they are — Dreams.
The bigger question is when do we find/invent the next non-hydocarbon base fuel system. Now thats going to be a daunting challenge but we will find it you can be assured.
It’s totally stupid. We don’t need a rocket plane that makes 12,000 km in 1 hour. So why not do Paris San Francisco in 10 minutes. We must stop with this obsession with speed. We have comfortable planes that move us at 900 km h we don’t need to be transformed into a rocket machine
Yeah in 2030 its going to happen.…. professional major league sports are going to want this
Concord emissions were calculated by cubic miles.
Yea not going to happen.
23 million in funding? Develop the aircraft in 5 years?
Interesting video thanks for posting. It would seem that hypersonic flight is a long way off, if ever. But there have been many things in the past that have seemed to be impossible, even flight itself. And at one time it was thought impossible to cross the Pacific by jet. The overriding showstopper would obviously be cost. Some commenters also mention G forces and sonic boom as showstoppers:
You only experience a G force when accelerating, so once you reach supersonic cruising speed there would be no G force. Everyone on earth is subject to 1G (9.78ms2) due to the earth’s gravity. And due the earths rotation, everyone on the surface is travelling, at around 1,600 kmh relative to space.
Assume a cruise speed of Mach 9 (343ms x9) and assume that you limit the acceleration to a hardly noticeable 1G (9.78ms2), it would only take 316 seconds to reach cruising speed from rest. (t=s/a where t=time, s=speed, a=acceleration)
The solution to sonic boom would be to fly at 153km, or higher where the air molecules are so far apart that shock waves cannot form. The proposed Venus Aerospace Stargazer illustrates the principle of flying high, with a cruising altitude of 52km.
Theres more merit in investment for mach 5 powered flight than there ever will be for the lithium battery powering reliable competitive aviation. A far better way to spend research and development money . This I support.
