I went ahead and removed Return of Jetman from a blogroll on this site, because there will be a lot fewer updates in its future. However, today is one of those updates! I have completed the revision for "New Return of Jetman" Episode 1's Notes and they are now back online. You can check them out via this link. Note that it helps to have actually read the story in terms of making heads or tails of them.
More Production Notes should be coming in the months ahead!
