Airlines agree to buy biodiesel fuel jointly

The Air Transport Associattion has made a major announcement concerning the use of alternative fuels, a topic I wrote about back in January when Continental tested a biofuel mixture in one of its 737 jets. This time, the trade group said eight airlnes would be testing the use of a biodiesel fuel in their ground equipment at LAX, starting in about three years. I found few articles about this, but here's one. 

Is it just me, or do we seem to be moving very, very slowly on development of new fuel technology in aviation? Yes, it's a tough problem to produce oil from plants in volumes that make it economically feasible as an alternative to fossil fuel. The infrastruture hasn't been built yet. But shouldn't we be attacking global climate change, and the role airlines play in it, with the urgency once devoted to putting a man on the moon?

Tell me what you think, and I'll write about it again this fall.
