I'm going to blame Google for this. They migrated the account I use to store images to a new service and the link format changed. Of course, I should have caught that too, but it obviously worked on my end.
It should be working now.
As for the ideas, they're just rationalizations for that weird little wart on the buttocks of the vessel. But that's half the fun, and history is full of weird-looking ships, planes, and automobiles; I doubt that's going to stop between now and the 24th 1/2 century.
