Firstly, a bit of Bletchingley my home village, five miles east of Redhill, looking due south as you sit on the A25.
We have an 11th century Norman church. It's a bit smaller than this, but I guess no-one will really mind



The layout of the roads is spot on, and the building opposite the church is the Whyte Hart pub (it's really not a bad likeness at all), dating to 1388.
I even added my house, at the very end of the village as you hit the fields. Just had to really

You can see Redhill AF to the south west in the middle top of the top pic- the hangars (which are orange in this shot=minor bug) are just visible.
Now onto Redhill AF
This is looking due north. The local railway lines were a very common navigation reckoning point for pilots returning home and are completely accurate in-game. The road systems and railways were perfectly placed by Rowan.
In fact the very straight east-west railway line was used by pilots in this period to locate most of the south London airfields of Kenley, Croydon and indeed Redhill. And so it is in-game.
You pick up the Ashford-Redhill line (in Kent, at Ashford) and can follow it for 50 miles or so until you meet the intersection point at Redhill for the London-Brighton tracks. Then you just turn right for the south London airfields.


Approaching Redhill AF from the north.

Home sweet home. You can see the hump of the North Downs a few miles away to the north. They are big enough to walk up, but aren't really terribly high, in truth.

Redhill AF was active through the Battle and War period. No squadrons were based there during the actual BoB (training was moved north as it was too dangerous around London), but many flew from there afterwards. Number 1 flew Hurricanes from Redhill in 1941.
