In my book, Everything We Had, I refer to aircraft no longer well known, even in the aviation world, and probably not among everyone in the “warbird” community. So here are some pictures and comments to supply the lack.
Most people at all interested in World War II aviation know two airplanes: the B-17G Flying Fortress and the P-51D Mustang. Great airplanes, but note the letters “G” and “D” in the designation. Those letters tell you that the airplane referred to is seventh or the fourth major modification, respectively, to a basic airframe.
In Everything We Had Captain Charles Davis and his crew fly a Boeing B-17D Flying Fortress, and between the “D” and the “G” lie a lot of changes. Compare these two pictures:
The above picture is a Boeing B-17D, the airplane Charlie and his crew took across the Pacific to the Philippines. Now compare that picture with this one:

The most immediately obvious change is the tail. Look how it goes from what the crew in the day called the “shark fin” to a longer fillet extending halfway down the fuselage. This was to give the aircraft greater longitudinal stability at high altitude.
The second most obvious change, well, gun turrets! The B-17D had neither power turrets nor a tail gun position, features that became standard after the “D”.
There were other changes like increased fuel tankage, better crew armor, greater bomb load, etc.
The B-17G was a more effective weapon for these changes, many of which were originally embodied in the earlier B-17E and B-17F. Nonetheless, our Air Corps went to war in the B-17D, because that was what we had to send at the time.
First in a series of posts about the airplanes in use at the time of my novels.
