My understanding is that the 22nd BG Association sued Hickey and IHRA years ago over the decades-long delay in producing the Red Raiders history, to the effect that after Hickey's death, the copyright for Red Raiders passed to the 22nd BG Association. I saw that they're going to be selling them for around $30, but I don't know how or when, or even if, they're having new printing done. It's an amazing price, but the book is easily worth twice that for the amount of work it represents.
I can certainly understand the families' frustration at having their memorabilia kept for 15-20 years while enduring multiple delays in publication dates, while the group members themselves were passing away without a book. But based on my own experience researching and writing about a single crew from the same theater off and on over the past 30 years, I can completely understand Hickey's position, which was needing to gather as much information as he could across multiple bomb groups while the men were still alive, and then having to organize, compile, distill, and finally write and edit the books themselves. Anyone who owns any of their histories can see what an awesome, daunting task they had before them, and how magnificent a job they ended up doing with them. They're incomparable.
