That comparison is interesting. What is it about planes that draws so much attention when something like this happens? It is barely news when a couple hundred civilians die on the ground in a war zone, but put the same civilians in the air and the whole world pays attention.
EDIT: Some people have mentioned that Gaza is all over the news but I would make the argument that the civilian casualties aren't what is making news. What is making news is the eruption of hostilities in the first place. For example, compare the coverage of Gaza to Iraq, Ukraine, etc. There have been several times more civilian casualties in numerous other active war zones this month, but they aren't new conflicts so news agencies aren't focusing on them.
