Still crazy to think those engines are as big as a 737 fuselage.
Even more crazy is the 105,000 lbf of thrust each produce, there is more power in 2 777x engines than all of the 4 engines of even the newest 747..amazing power
Airbus just showed off MAVERIC, their Blended Wing Body test platform at Singapore Airshow. Development started in 2017 and has gone into the scale model test flight stage at this point. BWB designs are supposedly 20% more efficient if the exact same engines and materials as the current gen aircraft are used, more if other newer tech is made available. Maybe we'll see more radical designs like this in a couple of decades.

On Tuesday at the Singapore air show, Airbus revealed one of its new technology test beds. It's called MAVERIC—short for Model Aircraft for Validation and Experimentation of Robust Innovative Controls, and it eschews the traditional airliner shape for a more unconventional "blended wing body" (BWB) design. This packs a lot more interior volume into an aircraft than one with a traditional long, thin fuselage would for the same overall length and wingspan. In fact, Airbus has been flight testing MAVERIC in secret; the project began in 2017 and first flew in June 2019. However, don't expect to fly on it any time soon—although it's airworthy, it's also only a scale model, measuring 6.6 feet (2m) long and 10.5 feet (3.2m) wide.
"By testing disruptive aircraft configurations, Airbus is able to evaluate their potential as viable future products. Although there is no specific time line for entry-into-service, this technological demonstrator could be instrumental in bringing about change in commercial aircraft architectures for an environmentally sustainable future for the aviation industry," said Jean-Brice Dumont, EVP for Engineering Airbus, in a press release.
One big hope for the BWB design is to make a more efficient airliner. Unlike cars, trucks, buses, or even garbage trucks, electric passenger airliners remain a long way off. Air travel is going to keep burning hydrocarbons due to their sheer energy density, whether those are biofuels or not. And if we can't replace hydrocarbon fuels for air travel in the near- or mid-term, then surely we could find a way to get people to their destinations while releasing less CO2 into the atmosphere.
The Flying V would be unlike any other passenger airliner, even in 2040
Airbus thinks that a BWB design should be about 20 percent more fuel efficient than a conventional single-aisle twin-engined airliner using the same engines. If that number sounds familiar, that's because it's the same fuel savings predicted by another BWB design we explored recently, the Flying V designed by the Delft University of Technology (TU Delft) in the Netherlands.
The amphibious Beriev Be-200ES with a rare paint scheme. It took off from the factory airfield today destined for delivery to the Russian Navy. Russia has such damn good livery for their aircraft while ours have the pizzaz of laundry lint.

That looks like a Dash 8 mated with an A10 Warthog.
Very close to the maximum crosswind vector for safe/comfortable operation of an A380 it would appear. A good pilot knows when to call it a day, and go around.
Anyone know what the wind and crosswind component was for the landing? The memo says that they would be graded a 1 in the sim, which would lead to me to wonder if they landed outside of limits.

Here is an onboard view, showing the landing from the tailcam. NSFW language on "arrival".
According to the thread on PPRUNE this was a different flight operated by a different A380. Original video is A6-APJ (operating EY19) and this one was A6-API (operating EY25). Looking over that thread EY25 shows a more correct version of getting the crab angle reduced before touchdown versus the original video of EY19.

I wonder if the A380 allows the traditional method of crosswind landings, or would that lead to a situation where an engine pylon could strike the ground? I have heard that the 747 can't do it for that reason.
Most airplanes, including the 737, have bank angle limits when doing a slip that would cause airplane parts to contact the runway. There are a number of charts that show different flap configurations, deck angles, and bank angle, which then show which parts will contact at what point (wing tip or winglet, engine pod, flap fairing).
Then it depends on what the SOP’s for that airline state for X wind technique, and bank angle limits.
On the 737, while it can land at X wind limit with 0 bank crab on landing, using some amount of bank will make the landing more comfortable. On the 800 the scimitar winglet would be the first surface to contact, on the 600 it would be a flap fairing usually (and at a much higher bank angle due to the shorter wing and no winglet).
All that to say I’m not sure what it is on the 747 or the A380.

Good catch, the tailcam of the EY25 landing does appear to be a lot closer to getting it right, and is likely battling less crosswind component.
The landing of EY19 is a mess, and I can't imagine anyone in the rear of that aircraft enjoyed the experience during those massive oscillations. Really speaks to the engineering of the landing gear of these large aircraft, the loads endured during that touchdown would be insane.
