I went cycling around Swinley Forest (The Lookout) this evening, and was just checking my route with Google Map's satellite view, and was quite surprised to see a very clear view of a twin-engined commercial jet flying over the Pennyhill Park estate near the Cricketers Pub on the A30. It is remarkedly clear and sharp given that it must have been flying at several hundred miles an hour. It might be a BA plane, and I assume it was actually considerably higher than it looks!
