Nearest flight is at Wattisham, so I imagine it would take 45 minutes or more to get airborne and down to where we are.
Headley Court is about 7 miles to the west - just to the east of the next gap through the North Downs at Dorking/Leatherhead. It was certainly heading in that direction once it turned west up the Kingswood Valley. Perhaps a transfer from Gatwick...?
