I posted this over in the references forum already, but I'l mention it here as well since so many of us have a Nightstalker or two on our benches.
There's a new book out about the 160th SOAR(A) that's $14 from Amazon ($20 retail)

I picked up a copy yesterday from B&N and it was published recently. Some of the images in the LB section we've seen posted here and in fact, you can tell the publisher used LoRes web images when they printed the book. I haven't had the chance to read thru it yet, but so far so good.
