Good luck Sebastian
I don't have the 17-40L but Paul has that one and its a good lens. I went for the cheaper option, because of a lack of funds and Simon you may consider this one too, the Sigma 24-70 f2.8 EX DG Aspherical. Very fast lens and sharp too but very noisy on the AF, lets the lens down a good bit but the quality is fab.

Get the 100-400. If you're thinking of blowing the cash strictly in terms of aviation photography, the lens is probably your best bet. And even if you have other uses, you already have a decent wide angle lens in the 18-55, so go for a better tele now. Aren't those Canons supposed to blow the Sigmas away?
