I know this story from day 1 when this e-mail circulated (a friend of mine, who's got a friend who's got a friend who recieved it and shared it).
Instead of sim hoax, read the real an live reports about unreliable airspeed events at cruise.
Undetected build-up => NO UNRELIABLE AIRSPEED TRIGGERED, no switch from direct law to ALT, no RTL control fault, no PITOT PROBE fault, No PFD Fault, etc.
If airspeed reached Mach 0.87 and triggered a nose up order, why the RTL settings would still show Mach 0.82?
Think about it.
