Back in February, Dr Moonie disclosed that he would consider leasing the base out - apparently Boeing was asked if it was interested!
At that time, he responded to the local MP as follows -
The Llanbedr facility has been operating at a significant financial loss. Last financial year there was an under recovery of £2.4m, this financial year we are expecting losses of over £3.6m. Keeping Llanbedr open would not only result in continuing losses of this kind, the requirement to re-surface the runway and obtain the necessary flight clearance for a new model of Jindivik would incur additional costs of over £10m. These are the facts, closing Llanbedr will save the taxpayer money.
I have found no news since this, apart from a mention in June about considering Llanbedr as one of a number of "regional" airports that could be set up in Wales, along the lines of those in Ireland, using EU grants to subsidise this "public" service! Better not hold your breath on this one.
