500 - cheaper compared to avgas, what was I meant. It's of course not cheap by any means.
But Jet A1 is half the price compared to avgas in Europe. And avgas can't be had readily at all airports. In the US Jet A1 is more expensive than avgas. On pure fuel costs, the case can be made in Europe that a turbine is cheaper to run per hour. That can't be done in the US. There's a reason all the diesel developments are coming from Europe
