I was going to mention the corner thing myself... Wow!! Look how close together they are now! I have noticed the columns for that part of 1 WTC slowly becoming diagonal. Every time I see these columns, I always think, "It looks like it's going to fall over" but then I remember that's how they're supposed to be. Lol. And now they REALLY look like they're going to fall over.
This is making me super psyched for my NYC visit - I will be there mid-June. So all the steel should be in place by then, the cladding I am sure will still be getting worked on and they should have started on the spire. Big difference from my last visit when 1 WTC was at the 83rd floor and cladding had just passed 7 WTC in height!
