I sense the undercurrent here is "how dare some mere civvy fly over this green and pleasant land (well, Wales) without requiring a chit signed in triplicate by some Wg Cdr". Well they don't. There's plenty of sky and even at hot spots like Mach loop the spotters sometimes have to wait hours between flybys these days. No prob so long as all parties operate professionally, as seems to have been the case here.
