I think you struck a nerve here because your entire argument is based on an assumption. Do you have any evidence he's endangering other people? Do you know something we don't, like there's a playground passed those trees, or he just pulled up in this public space and launched the jet without permission?

If not, then don't insult someone that appears to be extremely competent with years of experience, and call them irresponsible because you're jumping to conclusions.
