"Hi Guys, sorry to bother you but my airspeed sensors are momentarily unreliable and so autopilot and autothrottle will disconnect."
"Flight data was nominal when this happened and SOP in this situation is to maintain appropriate pitch and power while we sort it out."
Would you like to do that yourselves or shall I take care of it?"
Seriously, wouldn't that (or a more formal equivalent) have been a more helpful introduction to the situation than a flashing UAS alert & prompt disconnect?
After that, the "startle" response, inadequate training, mode confusion, poor CRM and other factors seem to led to the fatal outcome.
