Looking for a good video camera (airshows)

Hi fellow photographers i am after a good video camera for use at airshows must have good optical zoom on it whats a good one to get

You cannot go wrong with any of Sony's AX range, the ones that use balanced optical steadyshot are amazing, plus you can have other options within this range like 4K and built in projectors, personally I'd go with the AX53, it is very very good but at about 700 quid its not cheap.
