STARC-ABL, "Single-aisle Turboelectric Aircraft with an Aft Boundary-Layer propulsor”, sounds like pie in the sky if you look at ETOPS requirements.

I was recently on a modern cruise ship where all eight engines (propulsion and power generators) went out simultaneously for ~three hours. The emergency generator powered emergency lighting, navaids, comms, and little else. If we had been in the Greenland - Labrador crossing we’d made prior, it’d have been dicey.

A MIA - CDG STARC-ABL with the loss of one engine might theoretically find itself in similar circumstances., depending g on the interdependence of these dissimilar engines.
