Yes, Boeing still puts the RAT - ram-air turbine - electrical backup system on their planes.

  Why "still"? Even if the chances of a failure of both engines is almost zero, it has happened that there are losses of fuel. The ram-air turbine allows the pilots to have some instrumentation. That's super useful, for example in this accident: https://en.wikipedia.org/wiki/Air_Transat_Flight_236 https://en.wikipedia.org/wiki/Air_Transat_Flight_236

    “Still” because if you read the parent to my reply he uses that term in his query.

    > The ram-air turbine allows the pilots to have some instrumentation. Ideally, yes. I submitted a recent incident where the RAT deployed on a 777 because it's so unusual (and was also not due to lack of fuel): https://news.ycombinator.com/item?id=19039978 https://news.ycombinator.com/item?id=19039978
