they should be happy to be alive
Don't be so judgemental.
Unless you have suffered a life threatening incident, you don't really have any idea about the impact of PTSD.
Over 20 years ago, I was unfortunate enough to be caught in the middle of a nasty fire, where nearly 60 people died.
I was so close to the fire, that the flashover went within 20 metres of me, but for some reason I walked out without even a scratch.
After the event, I was fortunate enough not to suffer any PTSD and could have claimed a share of a compensation fund, but didn't, as I felt others needed it more.
But I do know that some of the other people were never the same again, had horrible flashbacks, depression and suffered recurrent nightmares and other severe impacts for years afterwards.
I imagine that some of the people on this flight would have my experience and others would be mentally scarred.
So you can score cheap points on a bulletin board, but you have not earned the right to comment until you have been there.
