Dont bother, the llib dumbocrats under the tutledge of nancy pelosi will stop any attempt to create any kind of fuel. She cant deatroy the nations ecomomy by using common sense and doing things to keep the nation infrastructure functioning. All attempts to do so will be choked and stifled by the libs in congress, cause just like oil drilling it cant happen for years. If we did something sensible it would make the marxist libocrats in congress look like the fools that they are.

So to answer the question, will greener planes fly. Yes, they will, just like redder planes or bluer planes or whiter planes. But not if pelosi and the marxist libocrats in congress can stop it. Maybe Obama will give us all a ride on afro-one when he is coronated and place on the throne by the marxist media.
