Atlas Control closes down at midnight tonight and R112 is disestablished, by which time all CAS(T) will also be disestablished . Unfortunately the WOD-OCK corridor will revert to being class A airspace.
There is a proviso that in addition to P114 and the two RA(T)s inside the Heathrow Zone, something resembling R112 may be re-established at any time if the government feel a 'need' exists..
