“their property”
It will be interesting to see where Freepers come down on this one.
Just like any other aircraft, balloons are required to fly above 500 feet (above ground level), except when taking off and landing. They also have to maintain 1000 feet over any obstacle within 2000 feet, horizontally.
As long as they are doing this, they are legal. "Property rights" don't include the air above you.
[Note: balloon festivals get a waiver of these rules, with certain pre-requisites]
When you start reading some of the local accounts in the Desert Sun this group starts to sound sort of whack-a-doodle. They spent the last ten years building a fortress, their attorney pulled his profile off of Findlaw today, and they’ve got all sorts of oddball maildrops for all of their corporate officers.
