I confess I didn't care very much for the title story; I didn't see much connection between the interleaved tales of WWI gallantry in the sky and modern day... angst? But many of the other stories are very good indeed. A couple of them draw from Van Pelt's day-job as a teacher, and those of us who have been in the trenches can vouch for the verisimilitude of the setting, even if we can't hope to be as inspiring as the teacher in "Mrs. Hatcher's Evaluation".
But my favorites from the collection don't have to do with school at all, though "That He Might Yet Find the Unknown" trades on another of Van Pelt's interests... running. It tells the story of the Olympics in the future, when genetically modified humans compete in the marathon. Like the best of these fables, that's what the story's about, but it's not what the story's about. I think my absolute favorite from the collection is "Rock House," a great and moody piece that is an inverted "Fall of the House of Usher" in which the house doesn't crumble, but rather becomes more solid. While the homage to Poe is clear, the story has its own tale to tell.
(Disclaimer: jimvanpelt was kind enough to send me an advance uncorrected proof of the book in return for an honest review. (and when the book appears on amazon, I'll post some version of this there.))
