So, to quote the poster that the plane "Hit a pylon whilst pulling out of a dive". Very well, but are there pylons in designated Aerobatic zones? Suprised in there are!
Aeros are not necessarily practiced in a designated areas. I have practiced aeros over unpopulated areas which I am sure contain pylons.
In theory you should never be low enough that pylons present a problem. 500 foot rule.....????
Its only when something goes wrong you wish they wern't there!
