just as I took this shot the air stewardess came and told me to switch off my camera!
She explained that because it is digital, I could interfere with the cockpit instruments.
I was rather miffed, never been asked to turn off a camera before, and if I had been using
the 20d, she may not have even realised it was digital so perhaps I could have taken
images of the beautiful patterns I saw on the ground below, of salt flats or something
which I saw as we were circling the airport....... :(
