Why can't this blended wing body trijet airliner fly?
As the comments point out, the main landing gear is too forward. Delta wings (and blended) typically land (and takeoff) with a high nose-up, should be an easy fix.
Left wing is longer, again easy fix.
Outboard control surfaces (normally would be elevons) are both pointing down on approach (or is it climbing?), tail heavy?
For a blended wing body, the airline still chose a tail-fin logo (backwards mind you)!
Natural pitch stability is required for certification, but the way it looks this design is unstable in pitch. Note that all trailing flaps are deflected down, something which will generate strong pitch instability. There is no obvious means by which a counteracting pitch response could be generated.
It looks as if payload is held mostly in the forward part. While it could be balanced when empty, with any sensible amount of payload it will be hopelessly nose-heavy.
