Besides being a stop for the local Islander and being used by the occasional Andover for the RAF visiting RAF Saxavord (where Shetland Radar was based).
It was used by Chevron and other oil companies to bypass Sumburgh after the new terminal was constructed and the landing fees went up accordingly. And as a diversion field/ fuel stop when the weather changed offshore. It only had an NDB the “UT” but its main advantage was the approach was over the sea and back in those days, you were allowed to let down until you had contact with the sea and fly in using radar.
There were 3 Bristow S61’s based there flying out to the Ninian North Central and South. The oil workers were taken up to Unst from Aberdeen, initially by 3 Brymon DHC7’s and then a fleet of 3 or 4 Loganair DHC6’s and then flown offshore. This activity stopped in the mid 80’s when the operation moved to Scatsta EGPM where the flights were shared with the BP (and others) workers commuting to work at Sullom Voe, and Unst reverted only to the inter island service and the occasional private flight. At the moment (10/2022) Unst is closed but there have been rumours of the Unst Space centre opening it again.
GBALZ the Bell 212 is probably rig based. There were a few rig based helicopters back then, used for inter rigging of personel and for Medevac and SAR.
The photo is hanging in the Unst museum and this is a photo of that one. I don’t know who the photographer was. Chris Morewood

Of course Unst is the most northerly UK ICAO designator.
The most southerly is of course…….. Rothera British Antarctic Survey station, unless of course anyone knows different!!!

And the island of Unst was the home of RAF Saxa Vord which was an air defence RADAR station. It was a CRP(control reporting point) for RAF Buchan. And in the ATC world it was the home of Shetland Radar. Today its been down graded to a Remote Radar Head, but there are still come RAF technicians based there I believe.

I visited Unst on 27 Sep 1972 when there was no control tower, just a runway, apron and a hut to house ground equipment.
No check in facilies; the passenger walked out to the aircraft and the pilot wrote out their ticket.
