Successful test flight for company aiming to travel London to New York in 1 hour
Venus Aerospace says it has successfully tested a rocket engine that could make hypersonic jet travel a reality.
It is hoped the engine could enable planes to travel four to six times the speed of sound from a conventional airport runway, making going from London to New York comparable to a trip to France.
The Rotating Detonation Rocket Engine (RDRE) launched from Spaceport America in New Mexico this morning, after months of testing in controlled conditions.
Sarah 'Sassie' Duggleby, CEO and co-founder, said: 'This is the moment we've been working toward for five years. We've proven that this technology works – not just in simulations or the lab, but in the air.'
Their ultimate goal is to develop the Stargazer M4, a Mach 4 reusable passenger aircraft, that would fly close to the edge of space.
Speaking with Metro before the launch, Ms Duggleby said the key difference with their engine compared to traditional rockets is that it is more efficient, so can carry less fuel.

Calling the tech the 'holy grail' of rocket engines, Ms Duggleby told Metro the main challenge was stopping it getting so hot that it melted.
'My favorite analogy is it's like lighting a fire in a wax fireplace, and you have to keep the wax from melting,' she said.
'It's really hot. So it's almost like you would send ice water through the wax to pull out the heat, and you keep doing that over and over again.'
She founded the company with rocket scientist husband Andrew Duggleby in 2020, and since then has secured millions of pounds in investment, and interest from Nasa.
If test flights continue to go to plan, a jet could potentially travel at 3,600mph and Ms Duggleby said that going from San Francisco to Tokyo could then become a 'day trip' in two hours, compared to the 13 hours it is currently.
Scott McLaughlin, executive director at Spaceport America, said: 'Spaceport America was created to make space history, and Venus Aerospace delivered a milestone moment for hypersonics today.
'Getting a rotating detonation rocket engine to the launch pad is an achievement few thought possible in such a short time. We're thrilled to host innovators like Venus, whose breakthroughs are redefining what's possible in spaceflight.'
The technology could go on to be used in both defence and commercial flight.
Mrs Duggleby said the experience of flying in a plane this fast would be much the same as being in a plane currently (except with a better view, as you would be further up).
Humans wouldn't suffer too much because we can withstand travelling quickly as long as it happens gradually. More Trending
'As long as the human body has gentle acceleration up to that speed, then we don't care if we're going 1,000 miles per hour, or 500 miles per hour or 20 miles per hour,' she said.
Andrew Duggleby, co-founder and chief technology officer, said: 'Rotating detonation has been a long-sought gain in performance.
'Venus' RDRE solved the last but critical steps to harness the theoretical benefits.
'We've built an engine that not only runs, but runs reliably and efficiently—and that's what makes it scalable. This is the foundation we need that, combined with a ramjet, completes the system from take-off to sustained hypersonic flight.'

Sir David Attenborough almost killed by faulty scuba diving equipment
To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Sir David Attenborough has detailed an unsettling incident in which he nearly drowned when scuba diving. The natural historian and broadcaster, 99, first appeared on screens in the 1950s, when he presented natural history programmes including Coelacanth and Zoo Quest for the BBC. His TV credits now span eight decades, with Sir David since presenting shows including Wildlife on One, The Blue Planet and Planet Earth, as well as the newly released film Ocean. However, he's now recalled a moment early in his career when he came close to a deadly situation. Speaking to Prince William at an event to promote his new documentary Ocean, Sir David was presented with an open-circuit helmet. Picking it up and putting it on his head, he spoke about testing a scuba diving outfit while filming on the Great Barrier Reef in 1957. 'When I put mine on for the first time I suddenly felt water and thought, 'this can't be right'. But by the time the water got about there I thought, 'I'm sure this is not right',' he said. 'Of course, you've got this thing screwed on top of you and you can't breathe or make yourself heard. I was saying 'get it off me'.' Sir David then spoke about the director leading the documentary initially refusing to take his concerns seriously. 'He grabbed it and said it was fine, but I again said there was a fault, and he put it on, and I'm happy to say, he went underwater and came up even faster than I did, because there was actually a fault on the thing,' he added. During the discussion Sir David also described his first dive as a 'sensory overload' and commented on how the reefs he first visited decades ago had now been devastated. 'The awful thing is that it's hidden from you and from me and most people,' he said. 'The thing which I was appalled by when I first saw the shots taken for this film, is that what we have done to the deep ocean floor is just unspeakably awful.' 'I mean, if you did anything remotely like it on land, everybody would be up in arms. If this film does anything, if it just shifts public awareness, it'll be very, very important, and I only hope that people who see it will recognise that something must be done before we destroy this great treasure.' The pair spoke as part of the promotional launch for Ocean, which sees Sir David 'drawing on a lifetime of experience to reveal Earth's most spectacular underwater habitats, showing that we're in the greatest age of Ocean discovery and highlighting its vital importance'. Sir David said he hoped the film could 'expose something new' and encourage viewers to act to save the destruction of the ocean. Despite his indelible impact on the world and environmentalism, last year his producer Mike Gunton told Metro Sir David hated being called a 'national treasure'. More Trending 'He hates it, by the way,' he said. 'I say hates it… If anybody says he's a national treasure, he sort of slightly raises his eyebrows and says, 'Really?' That's a generational thing.' When it was noted Sir David's work is of far greater importance than a title, Mike responded: 'You've hit the nail on the head.'

I'm an ex-flight attendant — there's unexpected protocol for medical emergencies
At 30,000 feet in the air, you really don't want to experience any kind of emergency, but these situations are usually outside our control, as Stephen Graham's story proves. The 51-year-old Adolescence star recently shared the 'scary' moment he had to have an emergency operation on a plane after urinating blood. During an appearance on Late Night with Seth Meyers, Stephen explained that he had a blood clot lodged behind his urethra and a surgeon had to perform a catheter procedure right there and then on the flight, which took place in a makeshift operating area between the economy and first class cabins. According to Del Wilden, an ex-flight attendant who worked with British Airways for 26 years, major medical emergencies like this do occur on flights but are relatively rare – he only experienced two in his entire time as cabin crew. In the event that this happens, there are some little-known protocols staff have to follow and Del, a former purser (Senior Cabin Crew Manager), has revealed them to Metro, as well as the one thing most Brits don't realise about cabin crew training. Fuel your wanderlust with our curated newsletter of travel deals, guides and inspiration. Sign up here. In the event of a medical emergency, Del says cabin crew would always start by asking passengers if there was a medical professional on board, and while they were ideally seeking a doctor, nurse or paramedic, there was one other profession help could be accepted from, and it might surprise you. 'We were always told that if a medical professional didn't come forward, but a vet came forward and was prepared to help, we were allowed to accept that, he says. 'We had to get them to sign a form of indemnity before they started to help and it would usually only be if a situation was so serious it warranted help urgently.' Until someone came forward, cabin crew would provide as much first aid assistance as they could and Del claims they have much more rigorous training in this area than most Brits realise. 'Until a professional came forward, we would act accordingly. So if it was a heart attack, we'd commence CPR immediately, while another crew member would gather equipment, like a defibrillator and oxygen, and someone else would keep the captain informed of the situation.' As well as being trained in CPR, Del says he was also taught to deliver a baby, in case someone ever went into labour during a flight. If there were no experts on the flight to help, cabin crew would be able to call a company called MedLink for advice in the event of an on board medical emergency. Each plane also had its own special medical kit on board known as an M5. According to Del, half of the kit was for crew to use, while the other half was intended for professional medical use, and this is where the catheter for Stephen Graham's operation would have been found. As well as medical emergencies, Del says there are two other types of emergencies flight attendants may have to deal with – pre-planned and catastrophic. A pre-planned emergency is a situation that develops during a flight and is something that cabin crew have been prepared to respond to. They'll have protocols in place for dealing with the issue and there's usually a bit more time to handle it. An example of a pre-planned emergency might be that the plane has lost its hydraulics for landing. In a situation like this, Del said there would be an 'alert call' over the PA system from the captain, who would ask the senior cabin crew to report to the flight deck immediately. 'As crew, if you hear that during the service you would put your trolley away and go to your station (door) and await a call from the senior crew member,' he says. When the senior team member returned they would then give their crew what's called a 'NITS' breakdown for the emergency, which stands for nature, intention, time and special instructions. For the hydraulics example, the nature of the emergency would be that the plane has lost the hydraulics, the intention might be to dump some fuel and for time, the pilot might have said they have about 45 minutes until they need to land. In this situation, Del says the special instructions could be not to evacuate the plane immediately once they've landed. Following this, the next step would be for the crew to brief passengers on the situation. 'We would go out into the cabin and we'd all have various positions. The captain would do a PA announcement and tell them that there's a situation and what's happening and then they would play a pre-recorded announcement,' Del explains. More Trending 'This always starts with 'Attention, attention, this is an emergency announcement' and then it would tell passengers to follow the crew's instructions.' He adds: 'We would always go through the announcements twice, because we were taught that passengers won't really take much in the first time as they'll be a bit shell shocked, but once you play it a second time, it starts to sink in.' For a catastrophic emergency, such as a plane crash, there isn't the same amount of time to prepare, so Del says staff who are able to do so would have to act instinctively on whatever the situation is. 'If you survive whatever is happening, there's no time involved to make a plan, you basically based on your training would have to use your instincts and find a way to get passengers out of the plane. But before you open any doors, the most crucial step would be to look for fire or any other kind of danger.' Do you have a story to share?

Rich people ‘will have robot butlers within five years - with one major flaw'
We've all had fears about it, right? That one day robots will come in and takeover the world? Well we could be getting that much closer, as one expert has predicted robotic butlers will be a common toy for the super rich by 2030. Right now, humanoids are making great strides (or sometimes, falling over), but are still not quite ready for mass adoption. The chief executive of a company which makes robots used in warehouses across the world says this is about to change, however. Romain Moulin, the founder of Exotec, told Metro that within five years, those with enough money to spare will have robots to wipe their floors and maybe even fold their laundry. It won't be because they are so good at the job, though: 'It's mostly for bragging to your friends,' he said. They will be an expensive novelty at first, and will work for far less time than Jeeves could before taking a break. 'I think the first one we'll see will be like a Roomba,' Romain said. 'It will be sitting in a corner of the room. You will have some friends over and you will tell that humanoid robot, 'Please clean my floor.' 'It will pick up a broom and start cleaning, and then will go back and sit on his chair charging, because he has ten minutes of autonomy. That stuff has high power consumption.' At a push, developments in battery tech might let it keep going for 20 minutes, but ultimately it's not going to last longer than a cordless vacuum. Romain's company makes the Skypod robot, a functional piece of tech serving companies including Gap, Carrefour, Uniqlo and Decathlon. He thinks that when it comes to warehouses, humanoid robots are destined for the scrapheap. 'Nobody has a convincing answer on why you would have legs instead of wheels for an industrial environment,' he said. 'Why would you want legs on a flat concrete floor? You will save half of your robot price by removing them.' To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video He isn't convinced that humanoid robots are the answer for companies trying to be more efficient. By replicating the shape of a person, they're optimising something 'to run in the bush and pick apples in the trees' because humans were built for prehistoric survival, not packing parcels. But he does admit they are more useful in places where humans tend to be, such as hospitals, restaurants, or houses. Bringing a robot home isn't simple, though, as it's a much less regimented environment. 'Payload, autonomy, and safety are the biggest challenges,' Romain explained. 'If you increase the performance of your robot and you want it to lift heavier things, you are creating more chance to hurt someone.' He said that for a robot to be able to stand and walk around, its legs would have to weigh some 40kg, which is already enough power to do damage. Do you want a robot housekeeper? Humanoid robots are becoming more and more high profile, made by companies such as Tesla, which says their Optimus model will be 'capable of performing tasks that are unsafe, repetitive or boring'. This robot is expected to cost around $20,000, but Romain guessed that fully functioning humanoid robot capable of doing household tasks independently would be more like $200,000. While we're fascinated by robots that look like us, they are more complicated to programme than a box on wheels. Balancing is a particular issue, and if it goes wrong it can lead to disturbing scenes like this robot 'going berserk' in a Chinese workshop. Romain says this is likely to have been down to its sensors realising it was still not stable, so making bigger and bigger 'crazy' moves to try and fix the problem in a feedback loop.

This is how Evri were able to test out a robotic dog to deliver parcels, and UK farmers have also embraced the tech with robot fruit pickers. You may not interact with them much yet, still, but they could become as commonplace as touchscreens for food orders soon. More Trending He said that he is concerned about the changes that are coming to the jobs market, with humanoid robots able to take on most unskilled work within 20 years, and computers just 'working alone' in offices. 'One human then will do the job of five humans now,' he said. Even though Romain works with robots them every day, though, he won't be putting a butler on preorder. 'I prefer human relations,' he said. Get in touch with our news team by emailing us at webnews@ For more stories like this, check our news page.
