The weather was suitable for the flight but would have required flight in accordance with IFR in the vicinity of the Mull of Kintyre
I think this "often used" quote is actually someone's
interpretation of the TAF for Machrihanish which really said.......
Among the TAFS was a forecast for Machrihanish issued at 1100GMT on 2 June 1994 and valid between 1400 and 2100GMT that day. The forecast wind direction was 130 degrees with a speed of 15 knots gusting up to 25 knots. The forecast visibility was 7,000 metres in haze with scattered cloud down to 1,200 feet and broken cloud down to 3,000 feet and temporarily throughout the forecast period visibility of 4,000 metres and broken cloud down to 500 feet. In addition it was said that there was a 30 per cent probability that temporarily during the forecast period there would be fog with visibility down to 500 metres and broken cloud down to 100 feet.
..there was a very similar actual from Machrihanish as well........
