Planespotting at Heathrow T-5

I recently found myself for the very first time at Heathrow's new Terminal 5. The views were very good, as the new modern buildings provide a considerably better view than any than any the old terminals, however, the terminal is totally monopolized by BA, so there was no much variety in the type of planes to be spotted. I have to admit, that the venerable 747 remains a very impressive aircraft though!
