Whilst accepting that what has been seen seems foolhardy, why do aviators so often seem keen to be highly critical of a form of flight other than their own?
There are now thousands of people flying paramotors and paragliders in the UK. Virtually every Summer evening on my drive home from work I see a dozen or more in the sky at once.
They have an enviable safety record, in fact it's so good that the ANO was changed last year to formally free them from regulation (previously they had been operating on annual exemptions).
Sure they are slow, but so are balloons. They are also limited in performance, but so are many types of aircraft.
In my experience, the vast majority of paramotor/paraglider pilots are dedicated, sensible and understand enough air law to be safe.
Like any activity, one or two will make errors or behave recklessly, but that's no reason for other aviators to suggest tighter regulation for all of these people.
