Talon Surprise Element?

I was just looking at some of the construction pictures of Talon. The one caption above a picture read workers are working far below ground level for a surprise element. The picture has two workers near a double mat of rebar with a pier on it. I'm sure the mat and pier are for one of the steel columns on Talon. Whats the "surprise element"? Or do they just mean surprising element?

I saw the same thing on the website. I think that they are basically talking about the immalmen and nothing that the general public has no idea of. It did catch my eye though.

But why would they have to be below ground level to work on the immelman. If you saw any other photos, the hole is very very large! But it is the spot where the immelman is going to be. Maybe it will be a picture taker thing or something. We will just have to wait and see!

I don't know, I might just be using logic, but don't the footers go down really deep? Yeah, I think I am right, especially when you are talking about the immalmen. That would be an area in which a great deal of weight and pressure will be exerted, so there needs to be a great deal of reinforcement, hence the large footer.
