Established aircraft manufacturers have a huge investment in riveted
aluminum technology. This material lets them delay the costs of climbing
the learning curve of pure composites. It may not be a good as pure
composites overall, but it can be used with conventional construction
methods. There are still open questions about bend radii and rivet hole
dimensions. We'll see.
