Not bad! Question though - are you exposing the highlights very bright on purpose? I'm just interested in the answer, because it seems to work pretty well for these images.
I am in a way, but not through equipment per se. When possible it's best to keep the audience out of the shot, the runway has varying strength of spotlights at different spots on the runway, usually the very end is the brightest, so it's good to get the model there, shoot with a pretty fast shutter speed to make sure the model pops out with the exposed light and the audience in the background appears as dark as possible.
