Nice, I've flown into Compton Abbas (beautiful airfield and a lovely day out) and I've also landed a 15ton jet on a short grass strip. But that one had vectored thrust..... Wouldn't dream of doing it in a 510. At least he's in the uphill easterly direction in that pic, any Mustang drivers care to comment on whether stopping on 800m of grass, or departing (presumably lightweight) would be the limiting pucker factor?
