Key legal question
Whether the municipality was entitled to compensation for direct overflights over its parcel.
Extracted holding
No compensation was due because the parcel was not regularly flown over at such low altitude that the property airspace was infringed.
Extracted reasoning
Only actual, regular, low-level intrusions into the airspace above the parcel amount to expropriation; the recorded flight paths showed the parcel was practically never directly overflown and most aircraft were well above the critical height.
