This Dick Smith - is he a pilot? His terminology is strange and he seems to be extremely fond of his own misguided opinions. He is of the 'Frankenstein Food, Global Warming' genre. Oh! and 'missing death by a hairs breadth' panic mongering breed of sub human.
Dick by name, "Dick" by nature, I would venture.
Radar apparently, solves all aviation safety problems so far encountered.
Australia is, thankfully in this instance, a long way from
the UK.
