When flying south from Glasgow to Southampton, we were relatively low as we came across the southern part of the UK and I spent a lot of time looking out of the window trying to determine exactly where we were. When navigating in the air it can be easy to convince yourself you are somewhere and then make whatever you see fit with what you think should be there. That can end with you badly lost! However, if you keep open to the idea, you can quickly establish your location. I thought we were in the vicinity of Oxford but wasn’t certain. Then I saw a circular building finished in what looked like stainless steel. I as pretty certain that was part of labs at Harwell. A check on Google Maps when I got home confirmed that is what it is. No, it isn’t the Apple campus!
