::: I've had a quick read through, and I pretty much stand by what I said. If it was nominated at AfD, I would support retaining the article, but I do wonder if the topic could be appropriately covered in the article on the book. Perhaps if there was too much in the "finished" book article on the plane, it could be split off (in the manner we have split off articles like the FA Development of Grand Theft Auto V). The other option is this: you could possibly have an article called something like "Technology in Tintin" to which you could merge these various articles; however, unless you have some literature talking about technology in Tintin generally, you could be accused of synthesis. Just thinking aloud...
