Thanks for the comments all.
Lens and camera – Bog standard Nikon D50, with a cheapo Nikkor 70-300mm which you pick up off e-bay for around £70. All the jets are shot on Aperture priority around f.8, all the props on Shutter Priority around 1/250th, to get a bit of prop blur.
It should be stressed that I shot off over 1600 frames – the more you shoot the more chance of getting a good shot is my view!
Also, there’s quite a bit of post-editing going on, contrast changes, sharpening etc.
As for the timing on the Reds shot, it’s not as difficult as it looks. I focus on one and fire away on a quick shutter speed in continuous shooting mode. After enough passes you are bound to get one opposition pass!
