I have to confess a true fascination for old planes left to rust on the side of an airport. La Paz - Jfk International (El Alto) Airport in Bolivia is a great place for that matter. Tens of very old planes can be seen all around, some seem to be in the process of being repaired, and some are...well beyond this point.
