When we last looked at air taxi startup Lilium, it was in administration and had laid off most of its employees on December 20. Now it seems there was a Christmas miracle on December 24, with investors throwing out a US$206 million lifeline.

On the heels of eVTOL startup Lilium shutting down, air taxi builder Volocopter may close its doors having filed for insolvency due to lack of funds. On December 26, 2024, the Karlsruhe Local Court in Germany placed the company in administration.

Some historic aircraft seem like a barrel for holding superlatives. One of these, the H-4 Hercules, goes one better because it's also at the center of one of the strangest stories involving possibly the 20th century's strangest man – Howard Hughes.

German eVTOL startup Lilium has ceased operations as of this week – sunsetting a decade-long effort funded with over $1 billion to build electric air taxis, with nary a single aircraft delivered.

BAE Systems has announced that STRIX, a new type of VTOL (vertical takeoff and landing) aircraft, made its first flight in late October. The flight was reportedly successful, paving the way for production of the unique aircraft.

Chinese "Space Transportation" company, Lingkong Tianxing Technology, has successfully tested its new JinDou400, also known as JinDouyun, ramjet detonation engine nearly twice the altitude of commercial passenger planes and more than doubling the Concorde's fastest speeds during its test.

While Australia's Airspeeder is yet to race its sporty eVTOLs with pilots at the controls, Jetson's founder and CTO Tomasz Patan has taken its One flyer to the air for what's been billed as the birth of the world's first eVTOL air racing.

Technology group Rohde & Schwarz has upped the ante in countering the threat of commercial drones to civil and military aviation with its Ardronis Wi-Fi system that doesn't just knock out drones, but infiltrates them and steals their data.

In a major development at the nexus of military and commercial technology, Archer Aviation and Anduril Industries have announced an exclusive partnership aimed at the militarized vertical take-off and landing (VTOL) sector.

NASA's X-59 aircraft has been marching toward a fest flight since it entered development in 2016 with the goal of bringing back commercial supersonic travel. Next, the agency will test jet-mounted shock-sensing cones to measure its "sonic thuds."

Another day, another wild electrified aircraft concept that reimagines the future of air travel. This time around, it's a turbine-electric hybrid that tilts its ducted electric fans to offer helicopter versatility with airplane range and efficiency.

One of the rotary engine's biggest champions, AIE has been advancing rotary design since 2012. Its latest release shows that Wankel engines can be a perfect fit for compact, power-demanding applications in robotics and aerospace.

A self-propagating series of explosions, contained between the blades of a high-speed rotor, promises a leap in power and efficiency during hypersonic flight – provided this radical new engine can be built strong enough to withstand its own power.

Even though today's aircraft rely heavily on GPS for navigation, the technology isn't infallible. That's why an alternative system is in the works, which may allow planes to navigate by "reading the fingerprint" of the terrain they're flying over.

Engineers at the University of South Australia have taken a page from the days of wooden sailing ships and developed a way for drones to navigate by the stars at night using simple, lightweight equipment for areas where GPS signals aren't available.
