Welllll......I just asked a reliable source and....yes it is confirmed that some luggage did go into the drink. Apparently the crew ACCIDENTLY lost their hold on a load of luggage and off it went. Some was hauled up and some was lost.
I do not know what the compensation was, so I cannot address that issue. All I can say is....unfortunately, sometimes we humans make mistakes. Yes, I know it hurts, but it does happen.
I hope the cruise line will take care of those whose luggage contents were lost. I somehow doubt it, but I will continue to hope. I also hope that someone will follow up with the resolution to this problem and let us all know what happens.
