Well, assuming you know about failsafe...... you wouldnt want to fly over schools, parking lots, rv parks or anything like that. couple weeks ago, there was a post where Jets were banned because there were houses a quarter mile away!! so again, i ask....not about failsafes...not about groundspace, or line of site....im talking reasonable AIRSPACE to pre-empt as best you can, this issue of our jets always being banned. starting with a clean sheet of paper, and planning something that is from the beginning, a jet friendly site. Im sure SOMEONE out there understands what im asking... what are your thoughts?
