Posts ghw78 (#1820) and Carlsberg (#2388) correctly state that Vref cannot be less than 1.3 Vs0.
That is in accordance with the certification basis as detailed in the B777 Type Certification Data Sheet on the FAA website.

Automation vs Seat-of-the-pants-flying
talking as devil's advocate - so no abuse please.
Occasionally the pilot has to intervene because the automation is not doing what the pilot expects.
How many times does the automation intervene because the pilot is not doing what the automation philosophy demands? It is probably under reported.
From my perspective the automation has lead to increased safety in the last decade and the odd exceptions do not invalidate this perception.
Most car enthusiasts have had to acknowledge that they can't repair an engine problem on the side of the road any longer due to the sheer amount of electronics under the bonnet (hood, for the cousins) even on my diesel Land Rover. But, you have to admit, modern cars are incredibly reliable, so it is a worthwhile trade.
That planes will fly without pilots within 20 years is indisputable. Driverless cars will come within ten years. And safety will improve.

Should the nose cone have more damage than this?

Hampster wheeling at max revs. Standing by for new, actual facts. Themes presently discussed can be addressed in Tech Log and Safety forums as they are now general and not specific.
