This is -very- speculative but it looks like the full horizontal stabilizer is missing, it's not a video/rolling shutter distortion the vertical stabilizer is partially visible in black, but from this frame the powerlines are visible where the horizontal stab should have been

Velos Rotors introduces V4 – pairing the robustness of a helicopter with the ease of use of a popular multicopter! 🚁
– Up to 120 minutes flight time & 11kg payload (80 minutes with a 4kg payload guaranteed)! ✍🏽
– Operating under any weather conditions (wind, dust, rain, you name it)! 💨
– Unparalleled reliability & safety – fully redundant twin transition design! 🛟
– Ready to go in seconds, with no maintenance required! ⏱️
This is not yet another UAV – it is an engineering marvel by the special team that keeps delivering to leading customers worldwide and pushing the industry forward...
Plus –and against recent 'best' market practices– this is not a mockup; the aircraft is actually available to order and fly as we speak!
Congrats to the team @VelosRotors on the launch! Contact them to learn more and integrate your very own payload starting today...

A quite similar incident occurred last year, Med Jets Flight 056, a Learjet 55 crashed with high velocity nose first to the ground

FIAT multiplay - exterior is nice but the interior is fantastic!
This is a concept, not a disguised production car but I hope this is the start of a trend to reverse all these hostile "piano black", dark claustophovic kitsch bunkers with huge pointless screens. Well done 👏

I have quite a few issues with this (it is part of a specific trend), however, some initial thoughts:
- it is shaped like a friend©
- fantastic materials and vibe inside
- having more of these rolling around makes the urban environment better, not worse
--> cool✅

You can unpretentiously resurrect just the “idea” / “vibe” of an older model (e.g. New Beetle), modernize the design and architecture for the modern age continuously (e.g. 911) or after a gap (Ford GT). Otherwise, you’re on the verge of turning your heritage into self-parody.

For everyone who's been asking: returning a Blackbird to flight would be very difficult and expensive. But there's one thing it can do, that nothing else can: launch large test vehicles at high speed.

As far as I know this is the first time ever that an airliner managed to land successfully after both the pilot and co-pilot were incapacitated. Two other pilots travelling as passengers and landed the plane after the crew and passengers took over. This is a crazy story
A new monopoly replacing Lockheed's. A couple of notes:
- Boeing lost JSF but never gave up, still on production just before F-47 arrives. Lockheed could and should do the same.
- let's see how close those two programs will be for better or worse

Such an awesome story, would be epic if this leads to a return to flight for an extraordinary aircraft: aviationweek.com/defense/air… By @TheDEWLine as well as @AvWeekGuy and @Free_Space

A SR-71 Blackbird Has Vanished
The head of NASA just cryptically teased a new X-plane with an image that looked a lot like the iconic Blackbird. Now a very particular SR-71 is missing.
