After this accident it became law in Italy that cabin crews have members that speak Italian. It seems that the passengers weren't able to understand the commands from the flight attendants before impact and after. I don't know if they were speaking English to them or not but for ENAC it doesn't matter. Italian speaking crew members are required for flights inbound or outbound in Italy.
Do you think that the SLF in Italy shall pass a ICAO level 4 proficiency test before boarding the plane?
