Has anyone seen the 80's animated series The Mysterious Cities of Gold? It took me forever to find it and before I did I started doubting if it even existed or if I made it all up in my head. It takes place in the 1500's and it follows this group that is looking for the lost cities of gold. At some point early on they find an ancient aircraft that is made of solid gold, solar powered and in the shape of a giant condor.
