I know of no such story as "Captain Stormfield's Trip to the Moon." Mark Twain spent about forty years working on the Captain's visit to Heaven; I don't believe that he or the captain took any side-trips on the way. Both Mark and Stormfield would be fascinated by these links between them and the Heaven's Gate group. I can only begin to imagine what Twain would say or Stormfield would do. Twain could certainly envision folks wishing to leave the planet he re-named "the Wart," and doing via a comet would capture his thinking. In another story, the character Mark Twain tricks his way into heaven by switching tickets with an archbishop because humorists are not welcome there; Twain says elsewhere that there is no humor in heaven, but he would note not only note the darkness of that event in California but also its dark humor. Truly, Twain appreciates the God's laughter Faulkner exemplifies in -Life in August- when he metaphorically pulls his camera high above the old farmer who, carrying Joanna Burden's murdered body from her burning house as her head, cut ear to ear, falls backward and turns completely around, says, [paraphrasing] "Well now, if you'd a-been a-looking that way when this happened, it might not've happened, would it?" Capt. Stormfield's story does not seem exaggerated compared to earthly events.
