Yesterday was the 66th anniversary of D-Day, the landing at Normandy. There were about 10,000 casualties that day on the allied side, 3,000 or so which were fatal. But yet people want a Google Doodle, logo, for the day.
There were a few posts from upset people in the Google Web Search Help forums with complaints. But the truth is, Google said they try not to do Doodles for events that are not light hearted.
