A project to demonstrate that jets could someday be powered by logging leftovers from Northwest forests gets a culminating test Monday morning. A Boeing 737 is scheduled to take off with fuel tanks filled partly with a wood-based jet fuel.

Alaska Airlines fueled a regularly scheduled cross-country flight from Seattle to Washington, DC with a blend of 80 percent regular jet fuel and 20 percent "biojet." In a sign of how safe the makers think this fuel is, the test flight will carry newly reelected members of Congress back to Washington, D.C., for a lame duck session.
