Fog has caused havoc with flights today, with no flying at all at Scatsta and most flights affected at Sumburgh.
A spokeswoman for Scatsta airport said that all 18 offshore helicopter flights to the east Shetland basin had been cancelled, and no personnel had been able to get up from the mainland on fixed wing aircraft. With no significant improvement in the weather due, the situation is unlikely to change for some time.
At Sumburgh the first flight from Shetland to Aberdeen at 8.15am was cancelled, as were the 12.10pm to Glasgow, the 3.45pm to Edinburgh and the 5.05pm to Aberdeen.
The flight which left Edinburgh at 12.20pm diverted to Kirkwall, and the incoming flight due to arrive in Sumburgh from Aberdeen at 3.25pm was cancelled.
