70-200 will be too short for flying aircraft. Depending where your standing, it will be good for when they are taxing to the RWY or close to the audience.
If you don't want to spend a lot, 100-400L or 400 f/5.6L will be great. Ideal choice would be 500 f/4L or a 300 f/2.8L with converters. If you have 2 bodies it makes things a lot easier.
For fighter jets, try and keep the shutter speed high as they are quick!!
Prop jets, 1/100 is a sweet spot to get full prop discs but it can vary and you might need to go as low as 1/60.
Very nice shots. I especially like the warbirds in B&W with the prop yellow markings, and the one of the Pitts Special. Well done!
