The makers of a luxury vehicle billed as a 'flying motorcycle' that can travel upwards of 300mph have completed flight testing their first prototype and are ready to take preorders, The Daily Mail reported.

Jetpack Aviation envisions its Speeder—a jet-powered, vertical takeoff and landing (VTOL) aircraft—as both a pleasure craft and a mission vehicle well-suited for medical teams and fire and rescue operations. The company's P1 prototype has an aluminum chassis and was tethered during recent flight testing in Southern California, where it hit several benchmarks that 'demonstrated the Speeder's ability to take-off, climb, hover, yaw and perform slow transitions into forward flight,' Aerospace Testing International reported.

The Speeder can reach an altitude of up to 15,000 feet and will ultimately be capable of producing a maximum thrust of 1,200 pounds.

With cargo on board, an automated Speeder could hit speeds of 300 mph, though a manned version would be slower so the pilot could safely see and breathe.

The cost of the Speeder was initially reported at $380,000, but that's likely to increase, according to Jetpack Aviation CEO David Mayman. The Speeder is small enough to be transported in a trailer and doesn't need charging before taking off.

Unlike a jetpack, there's not a lot of prep work needed to launch: 'You'd just hop on and fly,' New Atlas reported. JA is already working on its next iteration, the P1.5, which will use a smaller frame with carbon-fiber body panels.

It will look closer to the final production model and will fly without a tether. The next experimental model, the P2, will have a fully-formed body and small removable wings. While Speeder prototypes use four engines, the final production model will have up to eight.

JetPack Aviation has received backing from venture capitalist Tim Draper, an early investor in Elon Musk's Tesla and SpaceX, CNBC reported. Right now the Speeder can be powered by jet fuel, diesel or kerosene, but Mayman is committed to adopting zero-net carbon fuel moving forward.

Australia's burrowing echidna evolved from a water-dwelling ancestor in an "extremely rare" biological event, scientists said Tuesday in a new study of the peculiar egg-laying mammals.

With powerful digging claws, protective spikes and highly sensitive beaks, echidnas are well suited to a life shuffling through the forest undergrowth, AFP said.

But a team of Australian and international scientists believe many of the echidna's unusual traits were first developed millions of years ago when its ancestors splashed through the water.

"We're talking about a semiaquatic mammal that gave up the water for a terrestrial existence," said paleontologist Suzanne Hand, from the University of New South Wales.

"While that would be an extremely rare event, we think that's what happened with echidnas."

Echidnas and another Australian oddity, the semi-aquatic platypus, are believed to have evolved from a common ancestor called Kryoryctes cadburyi that lived in Australia more than 100 million years ago.

Researchers studied the single known bone fragment left by this ancestor, which was discovered among a trove of fossils at Dinosaur Cove in southern Australia some 30 years ago.

Platypus bones were similar to this ancient ancestor, Hand said, with a thick and heavy structure that provided ballast for diving.

Echidnas, in comparison, had very thin bone walls that made it easier to walk on land, Hand said.

This indicated echidnas were descended from a water-dwelling ancestor but had evolved to live on land, the research found.

It was far more common for prehistoric mammals to go from land to water, Hand said, pointing towards seals, whales, dolphins and dugongs.

The researchers said these findings appeared to be supported by other echidna traits.

Echidnas have backward-facing hind feet that help them shift mounds of soil when burrowing.

These feet may have first developed as rudders helping the echidna's ancestor navigate fast-moving waterways, Hand said.

Echidnas also have a "diving reflex" when submerged in water, which tells their body to conserve oxygen helping them hold their breath for longer.

Echidnas and platypus are monotremes, a rare group of mammals that lay eggs instead of live young.

"We're hoping we'll discover other ancestral monotremes that will help unravel the early history of this most fascinating group of mammals," said study co-author Michael Archer.

The research was published in peer-reviewed journal PNAS.
