Not at Abingdon, but certainly in Oxfordshire, lies the ridiculous P106 which is situated around Harwell. It extends to 2500 ft amsl and is 2.0 nm in radius.
Given, as this link
http://www.ukaea.org.uk/harwell/index.htm indicates, that the reactors were decommissioned nearly 13 years ago and that area is being promoted as the 'Harwell International Business Centre', I question the need for maintaining permanent prohibition of flight in this area. Particularly since it was only a Restricted area (R102 - and before that as EGR 14) with the same dimensions when RAF Abingdon was active, the restriction being that ac making ILS approaches to RW36 at Abingdon were permitted to enter the area! However, when RAF Abingdon closed, the restriction was no longer required and it became a Prohibited area.
This area is used by many GA aircraft, particularly those flying between Kidlington to Didcot to the east of the Brize Norton CTR. Anything which reduces the channelling of such aircraft into a common, uncontrolled area of airspace should be avoided; hence I have asked that the question of the continued status of R106 is taken up with the relevant authorities.
