Basically, this thread is about that stupidly unrealistic looking ‘A390’ you see on the internet.
Would any of these unrealistic planes actually be able to fly, and if yes, how? I’ll start.

Boeing Phantom Works
Boeing Phantom Works is the advanced prototyping arm of the defence and security side of The Boeing Company. Its primary focus is developing advanced military products and technologies, many of them highly classified.
Founded by McDonnell Douglas, the research and development group continued after Boeing acquired the company. Its logo is similar to the one used for the McDonnell Douglas F-4 Phantom fighter.
I think I read something before stating that Boeing wanted a passenger variant of it too. I am wondering, where exactly would the doors and windows go?
Well… If this thing is operated and flown by humans, then yes. Maybe some training for couple of years or months but if this is operated by again human beings, these are able to be operated / flown by humans,
Well I mean if you can make a remote control flying laune mower … and anything else as long as there’s a powerful engine and wings why not? Just scale it up😉
The A390 you say, huh?
Whoever made that April Fools joke about it here on the forum must have been a nutcase 😂
Oh wait… nvm… 🙄
Either way, i agree with what @Captain_Zen said. If you scale it up to the size of a commercial airliner and give it wings and engines, it would be able to fly. That is if you follow that laws of physics then as we all know those engines would give the thrust/power to move forward and those wings lifting it up just like any other airplane.
Edit: Gliders have wings, now if you glide through the sky you’ll create lift, right. So as long as you’re able to create lift that will keep you up in the air you must then balance the weight out on both sides. And once you’ve done that you’re able to fly. The engines as mentioned earlier gives you the power to keep moving forward in a steady speed. So it is possible for this concept of the A390 to fly… (the one posted here by the OP not my april fools thing, although that one could’ve worked but i doubt due to multiple reasons and flaws it carries).
In reality, it would never happen now. The A380 is barely managing and has four engines. So imagine six engines. I doubt there would ever be any orders, and that Airbus or Boeing will ever consider a four-engined airliner again.
Yes, i also doubt the six-engine thing. It would never work. Not by physics nor economically. It’d be just another A380 but even worse. And if the A380 wasn’t bad enough with taking up so much space at gates, taxiways and also economically being very expensive to operate then a six-engine aircraft can just throw it self out sky = stall and crash… because no one would want to operate it due to the high costs it would bring (Unless Emirates draws the “Save the A380 card”, but in this case “Buy the A390 with Six-engines cuz we can”). And it would definitely not be optimized for today’s airports. When the A380 was introduced many airports had to re-design and expand by making facilities langer and gates as well that would fit the massive A380. Even today many airports aren’t able to accommodate the A380.
It’s pretty much impossible to answer your question or similar questions such as “would it fly”. Years go into research and development before even a prototype of a new plane is introduced. No one on IF is qualified to answer this question (as far as I’m aware). If you really want an answer and not just guesses by unqualified people, I suggest you ask this question elsewhere.
Here’s a picture of a Qantas 747 beeing used a s a transporter for an additional engine. It’s obviously not in use, but it shows that there’s some spare space left.
Ironically the ‘lifting body’ technique, as demonstrated by Boeing, is a highly efficient design dramatically reducing parasite drag. B2 anyone?
If used for a commercial airliner then I would see the seating in the wings either side of the cockpit with windows in the leading edge. (Oddly enough where the aerodynamic pressure is low due to the flow over and under a thick chord aerofoil!) First class gets a pilots view! ;-)
The engines could be placed above the wing at the rear shrouding them from below thus reducing noise and assisting airflow acceleration over the upper surface of the wing aiding lift.
Huge lifting capacity, very slow approach and take-off speeds and low noise. The only drawback would be possibly a reduced cruise speed due to the thickness of the wing.
If not viable for passenger service then certainly I would envisage seeing a freighter or two.
