Dutch passenger Cor Pan was on Malaysian Airline flight MH17 with his wife when it was allegedly shot down by pro-Russian separatists, killing all 295 people on board.
Before boarding, Pan good-naturedly posted a joke on Facebook in reference to Malaysian flight 370 that disappeared over the Indian Ocean this year.
It reads: "If it disappears, this is what it looks like."
According to Buzzfeed, after the tragic events in the airspace over Ukraine, this was one of the first ways that family and friends even knew he was on the flight. They began sharing their grief in the comments.
They also set up a Facebook memorial page for Pan, where loved ones have posted pictures.
In reference to the events on Thursday night, the phrase "295 people" will be repeated over and over again. But we need to remember that for each one of those 295 people, there are hundreds or thousands of people mourning today.
Cor Pan's story is one of them, and for him and for every other soul on board, we cannot allow this tragedy to be forgotten - or go unpunished.
