This book provides detail photographs of the C-130 cargo workhorse and its variants.
The C-130 was the product of the US Air forces 1951 requirement for a tactical airlift aircraft capable of carrying 25,000 pounds of cargo for 1,100 miles. The winning proposal was that of Lockheed Martin that built the prototype YC-130A to start the long and impressive career of the Hercules!
I found the photos and information in this book to be fascinating and many of the photos are ones not available anywhere else. All major variations are covered in the photos and you see a lot of in-action shots.
These photos can be indispensable for any modeler building iconic aircraft. Each photo has a great description of what is in the picture, where, and when.
