R. M. Meluch’s Vati is a short story originally printed in the Alternate Generals anthology and since republished as a standalone ebook. It’s an alternate history with the divergence being Werner Moelders surviving and getting the wunderwaffe into service. Of course, the war still does not end well for Germany, with the Allies turning to something that makes a very, very big boom.
Although written before The Big One, and with likely no cross-pollination, I can’t help but think of Vati as “TBO done right”. Less rivet-counting technical accuracy to be sure, but a far more concise and far more literary way of illustrating the same point-“give the Germans their wunderplanes and see what good it truly does them.” Even without comparisons, this is well worth a read.
