Judge Fisher begins this opinion with the sentence:
"This is another maritime case about a train wreck."
Ho ho ho. I like a little nine-word humor to begin an opinion. (This isn't an original line by Judge Fisher, since Justice O'Connor used it in Norfolk Southern v. Kirby -- hence the "another" -- but I still love it.)
I'll let you read Judge Fisher's opinion to see why it's a maritime case even though it's a train (not ship) wreck. Let's just say that maritime law is a bit broader than you might initially think.
