I have to agree with him there. Far better that any training accidents happen over open desert.
When training for an air show, you want to practice around and over the city where the show is taking place. You need to learn where power lines are, where the tall buildings are, where the landmarks are that mark your turning points and boundaries of the air show. You also need to learn safe ejection places and a host of other concerns that can only be learned by flying above the site of the show.
All the citizens are asked to endure is "a little noise". Wow, what an enormous sacrifice.
Point conceded.
You'll note I didn't even address the noise issue.
