Of concern, to me at least, is what happens if two sensors fail at the same time in the same way (yes incredibly unlikely - but same sensor design/ heating, same drain holes - same cloud), the good sensor input would be rejected and flight controls act on bad-data for a short time?

What has happened to all the Thales AA probes removed from A/C - wouldn't it have been sensible to collect and inspect and look for signs of decay with age/ maintenance. I understand they are just certified scrapped when replacements fitted.
