Flying wings are nothing new. Are they remarkably efficient? Yes. Remarkably stable? Maybe, but not without tons of help.

There’s a lot of flying wing shapes holes in the desert from failed flying wing designs.

I'm a (admittingly old) aerospace guy and I just can't see this becoming a thing.

Delta wings are super cool and have a lot of benefits but inherent safety isn't one of them.

Modern commercial jets as we know them are inherently stable and a LOT has to go wrong before they stop flying.

Delta designs are kind of always barely flying and rely a lot on stability augmentation for optimized flight.
