And... Just in case people missed it earlier, the Thales pitot tubes were an optional fit. The standard was 3x Goodrich.
The Thales AA type are the only model known to have suffered a triple failure. The Thales AB type have suffered single and double failures, but not triple. The Goodrich probes have suffered single failure only.
There is no such thing as a perfect pitot tube design for weather conditions of that type.
