TIL that Frank Prentice a survivor of the Titanic, stated that the scent of the iceberg was detectable before the collision occurred.

I can smell so good- (tiny hand gestures) all right, you already knew that, but I can also SMELL very well, I have senses like they used to talk about, probably better than an Indian. I'm joking! But no, really, it's very great-

I can smell the beach, from so very far away you wouldn't believe it. Years ago, somebody says, on the drive out, somebody says "can you smell the ocean?" I say, "I've already smelled it for an hour. More like an hour and a half. Ask anyone, they'll tell you I can smell it from farther than anyone. It's, like, I'm a beacon, more like it's a beacon that I can see from so far away, only instead of seeing it, I smell it.
