I've just been re-listening to a recording that my brother made about when he flew on ops from RAF Eastmoor with 432 Sqdn RCAF in 1944 in Lancasters and Halifaxes. He describes the outbound and inbound routes as being from base to overhead Oxford and then over Beachy Head, and vice-versa. What really ticked them off was having to overfly the Lincolnshire area and having to flog on northwards to North Yorkshire.
