Yep, it does appear to be down.
On a slightly seperate note I hear on the grapevine that ABC are soon to introduce out of hours access of Oban, Coll and Colonsay.
I understand that it will work in a similar way to HIAL with a Indemnity Form being valid for 12 months at a cost of £30+VAT per airfield.
PPR and landing fees will be as per usual.
