Ha! First thing I looked for, can't find it.
I'll be interested to see people's reaction to the minefield that is the airport restriction warnings. As I discovered a while back, you can't swing a dead cat without hitting a 5 mile radius around some airport.
Also interested to hear what airport operator's reactions will be to the inevitable flood of calls they'll be getting now. Since they just have to be notified of a flight, not specifically approve it, airports are going to get a lot of calls they can only answer with:
"Hello, this is such-and-such airport. Ok, thanks for letting us know, just stay under 400 ft."
Ring, ring...
"Hello, this is such-and-such airport. Ok, thanks for letting us know, just stay under 400 ft."
Ring, ring...
"Hello, this is such-and-such airport. Ok, thanks for letting us know, just stay under 400 ft."
Ring, ring...
"Hello, this is such-and-such airport. Ok, thanks for letting us know, just stay under 400 ft."
Ring, ring...
"Hello, this is such-and-such airport. Ok, thanks for letting us know, just stay under 400 ft."
It's going to get old for them real quick.
