Interstellar

I watched half of interstellar.  Now I have to wait until the flight home to watch the other half.  This was the second plane.  No TV but a cracking view from out the window.

Guess where I am now.

a) In a SciFi movie
b) Travelled somehow back in time to some time in the late 70s/early 80s
c) Milton Keynes
d) None of the above
