I've net-tracked planes using an app on my iPhone.. PF AR

As I watched planes going down closer and closer to the horizon in the south,
I realized they weren't getting closer to the ground.
But the ground between us,
was coming up, between us..
Anyways, I found out that my eyeball is only good for small planes out to 26 miles..
Just watching them dip beneath the skyline of rolling hills,
I said, 'if I can't see them, I can't pickup any microwaves from them either'..
That's why I'm kinda amazed at picking up planes down below Long Island..
That's a pretty long haul..
