I only have the preliminary report, but I have to say that whatever contributory factors arose from AoA sensor failure, having recovered the a/c to 2320ft, 138kts and 7 degrees nose up pitch, it would appear to have been a failure to control pitch plus repeated use of aileron to pick up a fully stalled wing which caused their demise.
The HP removed the full nose-down pitch command, applied a hard nose-up demand and used full low-wing aileron at an unrecorded speed but probably below 100kts and possibly below 46kts.
