The first public test of the Hyperloop system went off without a hitch today in the Nevada desert.
The seconds-long, outdoor demonstration featured a sled of metal gliding across a 1,000 meter track.
The sled accelerated at 2.5G and reached a top speed of 400mph in just two seconds before disappearing into a cloud against the desert landscape.
But engineers still have a long way to go before building a full-scale working system that will eventually run at 700mph.

The seconds-long test run in Las Vegas featured what appeared to be a blip of metal gliding across a small track before disappearing into a cloud against the desert landscape. The test came nearly three years after Elon Musk proposed the Hyperloop system, which was dismissed back then as a 'pipe dream'
Today's demonstration focused on only one piece of a very challenging design, and was run on traditional rail tracks rather than in semi-vacuum tube to reduce air resistance.
'This is about validating the hardware and software,' said Hyperloop One cofounder and chief technology officer Brogan BamBrogan.
'By the end of the year hopefully we'll have a full test, with the sled in a tube accelerating with our custom propulsion.'
The sled bracketed to the rail was slung into motion using magnetic force generated by engines referred to as 'stators' set in a line at the start of the track.
This is a significant moment for us as a team,' Hyperloop co-founder Shervin Pishevar said to an invitation-only crowd seated in grandstand seats set up opposite the length of electrified track.
'We are standing on hallowed ground for us; the team has worked incredibly hard to get to what we call our Kitty Hawk preview.'
The US town of Kitty Hawk in North Carolina went down in history as the locale where the Wright brothers made the first successful flight of a powered plane in 1903.
The test under the Nevada desert sun was a step in developing a propulsion system that would give super high-speed motion to passenger or cargo pods gliding above magnetically charged rails enclosed in tubes.
This 'fifth mode of travel', as Musk calls it, could eventually take passengers the 380 miles (610km) from LA to San Francisco in 30 minutes - half the time it takes a plane.
The Paypal founder and boss of SpaceX and Tesla Motors, outlined his futuristic idea in 2013.
He challenged innovators to bring the dream to life and Hyperloop One, one of the startups that picked up the gauntlet, is hosting a 'sneak preview of the future of transportation technology'.
The California-based company says a full-scale, full-speed test of its technology could come by the end of this year.
That test will feature 3-mile track that will use tubes elevated above ground by pylons.
'When you think about passengers traveling on this, you will feel no more acceleration than you would on an airplane taking off,' BamBrogan said after the successful test.
After accelerating, the pods will essentially glide for long distances, making for smooth rides and low power consumption, according to BamBrogan.
'The goal of this test isn't just to move this sled,' he said. 'It is to engineer an acceleration system that is scalable for passengers and freight and to bring the cost down.'
'Today, we are one step closer to making Hyperloop real,' said the start-up's chief executive Rob Lloyd.
'We will be moving cargo in 2019, and we think we will have passengers safely transported by Hyperloop in 2021.'
Yesterday, Hyperloop One said that it raised $80 million in fresh funding from an array of investors, including GE Ventures and France's SNCF.
'The overwhelming response we've had already confirms what we've always known, that Hyperloop One is at the forefront of a movement to solve one of the planet's most pressing problems,' Hyperloop One co-founder Shervin Pishevar said.
Pishevar and Brogan BamBrogan founded Hyperloop One, originally named Hyperloop Technologies, in 2013 to make real Elon Musk's well-researched vision of a lightning-fast transport system with the potential to transform how people live.
A series of tweets fired from the Twitter account @HyperloopTech teased 'big announcements you don't want to miss' and included a video snippet of construction in the desert.
A caption in the video clip heralded a 'milestone event' that would be live-tweeted from Las Vegas beginning at Tuesday 5pm PDT (Wednesday 1am BST).
Late last year, Hyperloop chief executive Rob Lloyd said in an online post that the team was working toward a 'Kitty Hawk' moment in 2016.
The post came with word of an agreement to use an industrial park in the city of North Las Vegas to conduct a Propulsion Open Air Test of the blazingly-fast rail system.
Lloyd described it at the time as a very important step on the way to realizing the full potential of Hyperloop Tech.
'Our 'Kitty Hawk' moment refers to our first full system, full scale, full speed test,' Lloyd said.
'This will be over two miles of tube with a controlled environment and inside that tube we will levitate a pod and accelerate it to over 700 miles (1,125 kilometers) per hour.'
He indicated in the post that a full-scale test might not take place until late this year.
Hyperloop did not reveal what components of the system would be shown in a demonstration slated to take place Wednesday at the test site.
The Hyperloop project went live in 2013 on crowdfunding platform JumpStart Fund, which marries crowdsourcing expertise with crowdfunding.
That year, Musk unveiled a design for a super-fast transport system dubbed 'Hyperloop' that could carry passengers in low-pressure tubes at near-supersonic speeds.
The project could connect Los Angeles and San Francisco in 35 minutes in a low-cost alternative to a high-speed rail network planned for California.
Musk has said he has no plans to build the system but offered the 'open source design' to allow others to pursue a venture. He's called the system a cross between a 'Concorde, a rail gun and an air hockey table.'
Jon Favreau, director of 'Iron Man,' has referred to Musk as a modern-day 'Renaissance man.'
In an article for Time, Favreau said he and actor Robert Downey Jr. modeled the main character in the movie -- 'genius billionaire Tony Stark' -- after the Silicon Valley star.
Musk told Time that his goal was to be 'involved in things that are going to make a significant difference to the future of humanity.'
South Africa-born Musk has become one of America's best-known innovators, having launched a payments company, electric carmaker Tesla Motors, SpaceX and SolarCity, which makes solar panels for homes and businesses.
He also operates his own foundation focusing on education, clean energy and children's health.
Meanwhile, another startup that has picked up the Hyperloop gauntlet announced that its design is incorporating passive magnetic levitation originally conceived by a team at Lawrence Livermore National Laboratory.
'Utilizing a passive levitation system will eliminate the need for power stations along the Hyperloop track, which makes this system the most suitable for the application and will keep construction costs low,' Hyperloop Transportation Technologies chief operating officer Bibop Gresta said in a statement.
'From a safety aspect, the system has huge advantages, levitation occurs purely through movement, therefore if any type of power failure occurs, Hyperloop pods would continue to levitate and only after reaching minimal speeds touch the ground.'
After Musk published a white paper describing a futuristic mode of super high-speed rail transit, Hyperloop Transportation 'rose to the challenge,' it said.
