Landing on non-airfields by helicopters–it’s what helicopters DO!
You seem to know nothing about helicopter ops. Buildings? Have you looked at the helistops in most major cities? Wall Street in NY? Rooftop operations? Sao Paulo Brazil is one of the busiest helicopter places in the world, due to traffic congestion on urban crime–every large building has a heliport.
“Blowing junk around”. The article mentions “dust and debris”. Dust was obviously not a problem–nor was debris–no reports of it affecting the helicopter–“no harm, no foul.”
“Keep in mind that this is a single-engine helicopter.” I guess that means that cities should ALSO try to regulate “single engine airplanes.” Perhaps you should ask your city council to prohibit them (and don’t forget gliders and balloons!" (sarcasm)
The takeaway–THERE WAS NO DAMAGE–NO ACCIDENT–NOBODY HURT–ALL WITHIN THE LAW–yet you feel that YOU should be the arbiter of what the law SHOULD read?
