Heathrow T2 as never seen before

I was on the first flight out of T2 Heathrow this morning. Despite staying at an airport hotel I was still up at 3:30 as the taxis was booked for 4am. We checked in at 4:15am and then tried to proceed through security which was still closed. As the picture we were almost the first people airside. I have never seen a major airport so deserted.
