This week we remember those lost with flight MH370 on 8 March 2014. Lost - and never found.
This week, we also remember the earthquake and tsunami that devastated areas of Japan 4 years ago on Wednesday. Unbelievable images that you can't easily forget, if ever. Another tsunami, with even more devastation, passed its 10th anniversary last Boxing Day.
Let us not forget the innocent lives lost on flight MH17, when it was downed over eastern Ukraine last July, under circumstances that are less clear than you might surmise.
