There have been 2 new and 2 preloved trikes arrive on the shores of OZ (in case anyone didnt know). One of those trikes is a beautiful gleaming new green machine (and yes the Kermit jokes have been done to death)
Google Earth has a file you can download to see Airspace in 3D. (new to me, I had no idea)
This in conjunction with Skyvector is a great airspace learning tool.
Absolutely Fantastic!!
