As for me, No, I have never driven a vehicle after any alcohol, and why would that be asked to the person?
I see in the paper all the time where people get DUI's or get into accidents drinking. Still against the law, and stupid. But then again, it is still against the law, and they get arrested and prosecuted. So the fact it didn't hurt anyone and landed in the street median makes it okay? What if it did hit a child, or car, startled the driver and they hit a pedestrian? It is all hearsay and subjective. Bottom line is, be an adult, don't drink and drive and stop flying recklessly.
And for the person that replied not everyone has an open field or area to fly, if you don't have a safe area to fly and fly where this guy did, that is as irresponsible and the people you mentioned driving after drinking. Everyone being an apologist to this guy will be put in the same category, as will responsible pilots when someone does injure someone. And what would happen if something does happen, the video is reviewed and shows the pilot ignored all the safety factors, and more restrictions are applied. Sorry, take a look at the video more closely and not seeing how they are not spliced together at 1:54 and 1:55 mark because the buildings magically change.
