The beauty of this particular GB, which I'm in for the second year, is that Joe runs a tight ship and research is an important part, and in this case for something that many think they know a lot about, but there's always more.
Case in point, my subject the control tower at Ford Island. The structure that is there now was refurbished some years ago for the movie, and also was featured in the earlier movie TTT, where in both cases it looked more or less like this:
In point of fact on December 7, 1941 it was still under construction, and would seem to be one dark color. Missing was the office on top, it was an open platform.
There are quite a few damage photos of Ford Island taken that day from a high viewpoint, but they are not taken from that tower. They are taken from an airship mooring mast located several thousand feet to the south. And none show the other tower. The only photos I've found so far are the Japanese photos, in which the whole island is dark because of the early hour.
It's a real challenge, but I am hoping to find a description of the tower on that day.
