As I recall, the guys flying the Gimli Glider were not happy about the extra drag and the impact on glide distance.

Though they probably were happy to have hydraulic pressure sufficient to operate the flight controls.

That really surprises (and scares) me. I would have thought that Aircraft Design 101 would say
“In event of total power loss, the aircraft should still be controllable for a reasonable period of time”

I think it does say that - which is why the ram-air turbine is there, and why it pops out into the airstream when power is lost. By what other method can you run a hydraulic pump when no power is available?
