The Qinglan water bomber was a water bomber developed for the I-400 submarine. It could be folded to fit the needs of the submarine. Qing Lan's combat mode was a surprise attack or sneak attack. The way he appeared was described as smoke in the clear sky. It could be mounted on a submarine for strategic use. Qing Lan's main weapon was a Type 93 machine gun, which could also carry 800kg torpedoes or aerial bombs. Qing Lan's design and appearance were similar to the Comet Bomber. However, due to Japan's defeat, the plan of the Haruhakan water bomber was not realized.

I'm not sure specifically which 'book bomber story' you're referring to. It could be about someone who uses books in a devious or criminal way related to bombing, like using books to hide bomb - making materials perhaps. Or it could be a more metaphorical story where a 'book' causes some sort of explosive reaction in a situation, like a book that reveals a big scandal and shakes up a community.
