This is the AWWA Sky Whale, a concept for the next generation of aircraft.
It is supposed to incorporate next gen technology and materials to create a ‘greener’ aircraft, despite having three stories of passenger seating and a fuselage twice as wide as the largest planes today.
It’s engines will be hybrid, working off solar power as well as jet fuel. it has mechanisms to reduce drag, and thanks to lighter materials the entire airplane will be lighter despite its size. The jets will even be able to rotate up and down (like a harrier jet) to reduce the size of the needed runway.
The plane will be able to seat a total of 755 passengers and will incorporate all the luxuries you would expect to go with a plane that looks as amazing as that.
