My wife (usually known as The Family Controller) doesn't really have an input into the problem. I have an attic full of research.
I also have my den. As someone who flew the DC-10 for five operators, I sometimes call it my "Ten-Den" since I have many large photographs around the walls.
On my right, I have a library (professionally built) consisting of around 800 aviation books.
My problem is that my den is getting more and more occupied.
If I do not do something serious fairly soon, I will need to use a machette just to get to my computer!
P.S. I also have a complete set of Propliner but that is not even up for consideration.
