Some quick observations from the report:
From the report on side 12 it shows CC communicating "normally" with the tower just 19 seconds before end of recording/impact with sea. CC stated they could not determine speed nor altitude as all three instruments was indicating different values, this was 45 seconds before impact. Also at 56 seconds before impact the CC made a request due to weather, might they have been in non-visual conditions during the final dive? Truly horryfying reading.
