> Having motors along the whole trailing edge of the wing surely kills the glide ratio of this, right? The motors are running at reduced thrust and changed geometry during all parts of the flight. Regarding power loss: Last time I read about it in more detail, the impellers were organised in groups of 3, and you could lose one such module anywhere on the plane, even on the front canards, without issues. On the wings you could probably lose several. If you lose all electricity everywhere that would be a bad day, but the same is true for a modern airliner with fly by wire controls.
