I am very sorry to read about the death of this young Captain.
Leaving a wife and two small daughters is very sad... especially if their financial futures are not financially provided for.
I do hope.... if Qatar Airways do not have death in sevice insurance on their tech crew....this Capatain was wise enough to have his own cover in place.
Life Cover is cheap enough to purchase...and eliminates any future financial worry for the wife and children.
Please note...Both loss of flying licence cover and also accident insurance cover....are totally useless in cases like this.
