Wow, these pictures fascinate me! I was born and raised in South Jersey across the river from Philadelphia and was interested in how far you can see the skyline of Philadelphia and especially how far you can see the skyline of New York when I was growing up because we had relatives in Jersey City and it was always a thrill to be going up the turnpike and see the twin towers for the first time right at Exit 11 if it was clear enough. And I had always wished I could see the World Trade Center from a hill where I lived 80 miles away but my father explained how that was not possible due to the curvature of the earth. But on our countless travels down to the shore on Rt. 72, I was wondering if there was some place where you could see Philadelphia because there was a part of Rt. 72 and Rt. 532 where the scrub pines were that seemed to be quite hilly. And I remember seeing Apple Pie Hill on a road map when I was a kid and wanted to go there but because there was only a dirt/sand road to get there, my father didn't want to take the car in there.
I live in Florida now but I'm going to be in Jersey for a visit in a few weeks and after seeing these great photos from Apple Pie Hill, I plan to finally go there. And it got me thinking that maybe it's worth a look up towards New York too.
So I did some calculations.....
The distance from Chatsworth to New York is 68 miles, according to this link when you enter the two cities.

Apple Pie Hill is 205 ft.
The tower is 60 ft. but let's say you only climb half way up which would = 235 ft.
The roof of One World Trade Center is 1,368 ft.
The top of the mast is 1,776 ft.
Then you do the math with this elevation and distance to horizon calculator

From 1,368 ft. the distance to the horizon is 49 miles.
Then you add the distance to the horizon from 235 ft. on Apple Pie Hill.
It comes out to 20 miles.
Add the 49 and 20 miles and you get 69 miles (Chatsworth is 68 miles)
So what that means is on a clear day, you should be able to see the entire 400 feet of the mast of One World Trade Center above the horizon!
Being that it has a unique shape, it should be visible assuming it's a very clear day and you know exactly where to look.
It will be real interesting to get that view. But even if I can't see that, being able to see Philadelphia will be more than enough for me!
