Hopefully it's a natural accident...
You know it brought back the war, first of all I thought it was thunder, then I thought it can't be...
Perhaps I'm being an over-protective mother, but the more they try to convince everyone it's an accident the more I become convinced it's not. Repeating "it's an accident" every other sentence almost is like they are trying to brainwash everyone. They've been saying it since about 30 minutes after the first blast. There's no way they would know that soon, especially when they couldn't get near it.
