Be nice to your co-pilot...
Complete hydraulic failure, interesting topic.
SV very nearly had one some years ago when a wheel burst at altitude, rupturing hydraulic lines, leaving only one half of system D available on a TriStar. In this case, only the First Officer can land the aeroplane.
They were very lucky a small amount of fluid remained, so the F/O could do the job he was trained for...and well done too.
