Very sad news, and a loss of one of the great characters in aviation. He had an ability to bring common sense to a situation, which coupled with his gentle good humour, made his contributions that much stronger. My personal best memory of Paddy was his help in designing overflow parking at Learmonth for heavy jets which could be diverted there. The most attractive option allowed considerable extra parking but had tight clearances and only just met all the standards. Not the best for aircraft diverted after many hours of flight, taxying at an unfamilar airport in a remote area which is a real 'black hole' at night. The least attractive option had less parking but was simple and open. Rather than a long debate about the pros and cons of all the issues and standards, Paddy simply said 'sure and you've got to leave a little bit for God'. The simpler parking option was chosen.
