Yeah most of these were taken from the aviation park. (Free to get in if you dont park your car).

I was using my 70-300mm and it was just right.
When they are on the nearest taxi way to the aero park you have only a few moments before you cant fit the plane into the pic with 70mm.
However for when they are positioned on the runway and takeoff, or getting the shots as they come off the apron then the 70-300 is perfect.
