Need help retracing context: 1950, on an airfield in Berlin, RAF uniform and British journalist

My grandfather was a British journalist working for the Daily Express, and he traveled all over Europe for work. He is the 4th person from the left, and the 3rd person from the left is his wife. We don't have much information about the picture besides the fact it was probably taken in the 1950's in Berlin, on an airfield. Can anyone spot any details which might help us identify the context ? Any suggestions very appreciated !
