London development plans "sky pool"

I am not sure that I could swim in this pool.

 I agree Jonathan! When it's done, I'd like to photograph it from a safe distance, but I don't  even think I could walk under it.

I suspect it's going to look quite a bit different "as built," since I notice that in the picture, the water runs right to the edge, and one side hasn't even a place to sit! By the time it's done, there will need to be an ugly wall to keep bathers in, and keep water from splashing pedestrians below.

At ten stories above building walks and parking lots, I'm not sure the view down through the pool will be worth it, either.
