You never know who amended it, but this is from Wikipedia:-
In recent years, the site has been used for agricultural purposes under the terms of an agreement with the Welsh Government, the current site owners.
It was reported in February 2008 that Welsh Ministers had awarded preferred bidder status for a 125 year lease to the operators of Kemble Airport near Cirencester.[2][3] In May 2008, the Snowdonia Society, the Brecon Beacons Park Society and the Friends of Pembrokeshire National Park formed an alliance against the development of a new civilian airport at the site without a full public debate "best achieved by making an application for planning permission".[4]
This campaign has been opposed by members of the local population who are in favour of the reuse and redevelopent of the site. A paper-based petition in favour of Kemble's plans for the airfield attracted over a thousand signatures, while an e-petition from the Snowdonia Society received 156.
In December 2008, the Welsh Government gave the go-head for Kemble to take over the airfield, subject to Kemble obtaining the "relevant permissions and consents."[5] In November 2009, the Snowdonia National Park Authority took external legal advice and refused to issue certificates of lawful use to Kemble. In August 2011, a certificate was granted to Llanbedr Airfield Estates for use of the airport to test and develop unmanned aerial vehicles.[6]
A quick google finds this:

Which shows the responsible person as David Young - nice chap, I used to deal a lot with him when he ran the microlight school at Kemble.
David in the meantime is clearly still active as a microlight FIC, as shown here...
