This is my two granddaughters standing in ...

... the middle of a deserted WW2 RAF runway in the New Forest. 

I had no idea that these things were still around after 75 years, but there it is. And look at how huge it is. I was under the impression that it would be much smaller with just enough room for maybe two Spitfires to take off side by side, not wide enough for a jumbo jet to land!.
