UA A320 at DEN: "Total Hydraulic Failure"?
Plane landing at DIA towed to gate - The Denver Post
In short, the report says that UA418 landed safely on 34L at DEN with a total hydraulic failure. As in NO control surfaces.
Has anyone here heard anything about this? The story has received virtually no attention, suggesting either the media is incorrect either about the extent to which the airplane was crippled, or simply has no idea what a "total hydraulic failure" generally means for the folks trying to fly the airplane.
As I understand it, an A320 that's lost all three hydraulic systems has no control whatsoever other than differential thrust, ala UA232. "Mechanical Backup", the mode to which the plane reverts in the event of a complete electrical failure, simply allows for the manual adjustment of the hydraulic valve of one of the trim tabs.
*Update: Just heard from a family friend with the FAA - so far, the official line from them is "Landed with total hydraulic failure."

Incident: United Airlines A320 near Denver on Oct 21st 2009, hydraulics failure
This clears things right up - only lost one of the three.
