ABOUT THE COVER
Nearly 100 years ago, the Wright Brothers used the engineering know-how developed in their bicycle shop to open a new era in aerospace. Today, advanced aerospace materials are coming back to earth as, well, bicycles and other sporting goods (such as Alyn Corporation's Boralyn bike frame). For a discussion of this topic, see this month's NEWS & UPDATE and the article that begins on page 15. (Photo by Cydney Conger/*West light.)
