those are some really, really nice shots you got there! A wealth of dynamic action conveyed through them and the texture of the sky and smoke trails adds a strong three-dimensional feel to them.
My personal favorite among them is actually the first one, to a great extent because of how the sky looks.
However, I found myself pouring over the whole series really enjoying how well you captured the feel of these jets.
In a few places there's a little purple fringing in the highlights - secondary lateral chromatic aberrations. It's an artifact of your lens-glass. You need a truly apochromatic lens, which costs too much to even consider. Since you clearly had to take these shots from quite a distance and since you have no control of the Sun's position, there's really very little you could have done to avoid this - if you care about it, some careful post-processing can help adjust for this.
Thank you for sharing these - this is some of the best action/viation-shots I've seen in a long time!!
