pedal - I had exactly the same 'interesting' experience as you landing at Heathrow once coming back from Belfast.
The woman behind me started praying extremely loudly which far from comforting me made me even worse amidst all the lightning flashes.
I had to be stoical though as I had my younger brother with me so I just sat there with a fixed grin on my face, even though I was absolutely terrified.
My brother loved it.
