Several major airlines have test flown bio fuels. They have indicated they will order them as production ramps up.

The DOD is contracting for bio fuel right now, including aviation fuel, see links below.

Please note that “Green Crude” is absolutely biological in origin, and thus products made from it certainly qualify as green. Butanol (which I mentioned) can be made from either crude oil or biological sources using the ABE (Acetone- Butanol- Ethanol) fermentation process invented nearly a hundred years ago by Chaim Weizmann, the first president of Israel. Today there are many variations and improvements on the process that increase the butanol yield.

But hydrogen, ethanol, and other such direct substitutes are simply not up to the task, for the reasons I listed earlier.
