Barnaby, I realise all of that, but without seamless CAS and easyJet demanding release directly into the TMA, flying out of Southend without full Class D is spicy! Just ask Air SouthWest (if they were available to speak) how many close calls their weekly service into Oxford had! They pulled the route after one season! Or their insurers did?
A lack of radar hindered their operation whereas Southend will have H24 coverage.
TAG are desperate for CAS around Farnborough and rightly so. The sooner Southend gets permanent CAS the better.
