Yes, it’s looking more and more like the 447 crash. The latter was really due to the faulty pitot-head design, and resulting icing and air-data failure, which made the TMR FCS fail, which turned it over to a back-up mode that wasn’t expected. Of course, Airbus couldn’t afford to take the aircraft system blame so the pilots were blamed. SOP in so many cases.

The pitot tubes only stayed frozen for 60 seconds. Nobody on deck seemed to notice. Other crews have dealt with frozen pitot tubes safely.
