Wasn't there a plan to put in a tarmac runway and ILS at Redhill? If I remember rightly, the idea was to put in a link road to the M23 and a new railway station and send all the little commuter turbo-props there, thus opening up more slots for big jets at Gatwick. Seemed a sound enough idea to me at the time, but needless to say, a small bunch of local nimbys kicked up a very big noise and the whole thing got dropped.
Hope this new body can do what needs doing.
