question about taking good pictures at Airshows

Hello everybody,

I’ve got a question about taking pictures of (fast) flying jets.
I’m going to an Airshow in Leeuwarden in July, and I’m wondering what kind of lenses do I need, to take good picture’s?
And which shuttertime is advised?

Maybe you have more usefull tips?

Thanx,

Evert
