One thing I've never seen explained is the half-tubular corrugations on the bottom of the airfoil that they both have. Maybe they are for strength. There certainly is a lot of leverage on the attachment point both cross-wise and length-wise.

There is a lot of concern about what happens to all those little pieces when two cars make contact.
