Frank Reade and his Flying Submarine is a new one. I'm surprised Noname didn't get around to combining the three basic elements before. But of course, no, this isn't a flying sub. That would eat into the Flying Machine time, which is strictly defined as 33.3% of all Frank Reade stories.

I haven't read the whole story, but I'm sure there's a good reason for cutting the iceberg in half, instead of just going around it.
