[monocoque]

I'm in the process of removing the lower interior skins to access the floor channel. Eventually this shell is going to float! As I suggested previously the screws around the window molding are either stubborn or rusted or both. After I removed the window molding I discovered that the lower window frame support (not sure if this is the correct term) was completely detached from the window frame itself! I suppose it was only being held up by the molding screws! Now how did that window frame support detach from the window frame with all those rivets!? I was guessing that the window frame rivets somehow missed attaching to the support frame but the holes are there in the support framing and the window frame seems securely attached to the outer skin. I love the mystery and discovery involved in this work!
