Zones and things.
Don't know why there is so much ill-feeling about protection and safety; regulated airspace merely provides a known traffic environment and is not an exclusion zone. As for traffic levels versus safety case have a look at the Bristol Zone.....just about wider than a 737's wingspan [artistic licence]; besides which it has taken 60'000 air transport movements a year and at least a decade of asking before they get a little bit more protection next year [hopefully].
No competent pilot should fear change, but beware the bar-prop bore who hasn't read a document or bought a new map for many a day as he does his thrice yearly spin in the cobwebbed hangar queen and then says.....Gosh, is that airfield active?...must write to my MP.....outrageous!
