Current speculation around the raising of flaps suggests that independent engine failures weren't the cause. Proper investigation with access to better data than grainy video will tell us if that is the case and why.

"4 smaller but equally efficient engines" feels like a unicorn though (we'll probably get to the point in future where four large engines are superior in efficiency to two of today's engines, but two large engines to that latest design will still be more efficient than four smaller ones...)

With turbines, yes, for fundamental reasons. With electric motors, on the other hand, perhaps not, though not particularly relevant to a long-haul route like AMD-LON.

True. Also the electric/turboprop propulsion compromises like Heart Aerospace's that trade off the limitations of the respective powerplants by fitting pairs of both. But that's a different use case...

(I get to write about arrayed space thrusters in the day job too, but again, fundamentally different physics and goals...)

It's pretty clear what the guy is inquiring about.

Speaking as someone without aerospace engineering or GA pilot experience. My only relevant experience here is being able to read.

Double bird strikes are “independent powerplant failures.”
