What about the A320 that crashed into the Mediterranean with 3 airbus test pilots on board?

They omitted an item on the Air Test Schedule, as I recall, and didn't want to climb back up to the recommended safe altitude to carry it out so they checked the low-speed protections at an unsafe altitude (3000ft) with tragic consequences when they AoA probes froze due to water ingress. Had they been at 14,000ft which is, I believe, the recommended altitude for the check they would probably have recovered from the stall.
They were not Airbus Test Pilots - they were a regular crew from XL Airways, with observers from Air New Zealand and the NZ CAA, doing a leasing/ownership handover flight. This, along with the Easyjet B737 Maintenance Test Flight serious incident in the UK, was the catalyst behind regulators enhancing Maintenance Check Flight procedures and crew training - precisely because the crews that perform these tasks are generally NOT test pilots (nor need to be).
