I thought they were already flying some on fruit and veg
Are you talking about something like biodiesel, or are you talking about ethanol, or something else?
I don't think it's a good idea to make fuel from fruit and vegetables because it will drive up the price of food; as for biodiesel, you don't need fruit and vegetables to do that; you can make biodiesel from deep-fryer oil, methanol and lye.
Actually, the B-52 flew on (and is now certified to use) a Fischer-Tropsch fuel derived from natural gas.
It was a USN F/A-18E that flew on a 50/50 blend of conventional jet fuel and a biofuel that comes from camelina, a hardy U.S.-grown plant that can thrive even in difficult soil.
However, various private and commercial jets have flown on various bio-fuel/jet fuel mixes.
