Alternatively, my own airfield at Wycombe can also be reached by train, but it's too far to walk from the station and you'd have to get a taxi.
There is also a bus service from the centre of Wycombe past the airfield which runs hourly, and another which runs every 15 minutes which would drop you about half a mile away. I've never used it myself, as I drive in from Oxfordshire.
