Once again I looked at a flight radar last night at a peak time in the UK, glad to see its working over here, approx 30 aircraft in the air over the whole of the UK, none here in Scotland. (well done to the UK), some of which were overflights and the remainder mainly cargo flights and emergency flights. Then looked at the USA, thousands in the air all kinds passenger, corporate etc they will learn one day, hopefully before its too late.
