Recently flew with Emirates, Heathrow to Jakarta via Dubai and first leg was on the A380. Apart from it being an amazing piece of kit, there is a choice of nose mount, tail mount and down facing cameras, selectable on the IFE screen.
Have to say the tail mount view is incredible. Just before the trip I saw a Richard Hammond TV program about the challenges facing the designers of the 380 wing and how they had used a bird wing as a template, enabling them to use a shorter span design. You almost felt that you were looking down from a hawks head. Incredible! And a great in flight bar too, though that wasn't mentioned on the program.
Also was fortunate pre 9-11 to get a jump seat into both Heathrow and Gatwick and thoroughly enjoyed it. Such a shame that my kids will never get that chance.
