@a4f53431 From the video (and looking into some of the specs I can find online) it seems like the "backup plane" B-32 was comparable capable with far less risk and cost. Is there documentation about why they didn't ramp up production of that bomber and ramp down production of the B-29? Sunk cost fallacy? 

 @Hank G ☑️ @a4f53431 Hadn't he said in the video that the "backup plane" hadn't got the same range? 

 @9d890fa7 @a4f53431 "Ferry range" of the B-29 was 5200 miles but I can't find a comparable number for B-32. Standard range for the B-32 was a bit longer than the B-29.
