Well it's been blamed on the windfarm, the SIC and Orkney's had its name dragged through the mud.
After reading something somewhere on the internet, I'm sorry to say it's none of the above; it's Brexit. The EU simply won't let our British flies in without the correct paperwork so they're having a staycation.

Word also has it Boris Johnson has awarded some multi-million pound clean-up contracts to mates fae his school days and the SIC have agreed to pick up the bill.
