I come late to this argument.
It sounds like a case of mis-communication more than anything else.
The real question you lot should be discussing is why fire and rescue services have to be provided for landing a helicopter.
If one were to take off from an airport that was closed after normal business hours.....would you argue the operation was unsafe because there were no fire/rescue services available?
A second question would be why there are not more roof top heliports available for use in urban areas.
Why is it places like Los Angeles can have hundreds of roof top heliports and the UK/Ireland have none?
The third question that begs discussing is why anyone would call this a "nutter", describe him as having performed "poor airmanship" and immediately hang him from the town gate.
What is it that this fellow did that is so out of the norm that he belongs in the "near lunatic category"?
The concept single engine helicopters cannot operate safely over "congested" areas and only multi-engine aircraft can is yet another question to be argued.
Perhaps we should have Nick remind us of the engine failure rates for singles and explain the inherent risks to operating a "Twin" outside full CAT A performance standards?
The final question that needs to answered, as one of my friends suggested over a lovely curry in Horley, is why Brits seem to pounce on others and tear at them like dogs at a rag, when things like this occur? He wondered whether it was unique to the British as he had not seen such events amongst the Americans, Canadians, or the Australians.
