Sir Niall....there was also the well known airline not many moon's ago that was crossing the Atlantic on a route 56N 020W 56N 010W....finger trouble had them input an extra zero for the 10W co-ordinate.....so yes as the flight crossed 20W it started a turn back to 100W.....after regaining the situation and outside radar cover the crew said nothing.....they were found out though as they entered Scottish airspace and once again under radar control they were now behind the aircraft that they should have been ahead of!!!
So as we say these £15m offices are fine as long as their is now human interaction!!
And as for the boat I am boat less at the moment.....maybe another year or two before I join the sailing ranks again.
Regards FBW.
