I was flying low about 2500' along the California Coast from Oceanside to Santa Barbara. Somewhere over Malibu I looked down at a construction site and saw what looked to be like a airline diaster, I couldn't believe my eyes. I circled, took pictures with my iPhone and realized I was looking at house being built using very large aircraft wings and primary structural elements. Googled it when I got home and sure enough. Check out this amazing project. Read about on this incredible project on treehugger.

By the way, recycled aircraft are not an invention of the 21st Century.
