CORRECTION - 1/1/2008

In the November 2007 issue of HPC, our p. 26 story on carbon fiber use in friction applications, “Friction products: Carbon fiber stopping power,” mischaracterized the energy of a fully loaded 767 landing as generating 737,000 ft-lb of force. Foot-pounds are a measure of energy, not an expression of force. HPC regrets
