Just back from my trip to see london. I saw a lot at heathrow, I will definately get back to shoot there sometime!
First, my both BMI flights were Star Alliance planes, G-MIDX and G-MIDW.
I stayed at the Ibis hotel, next to the approach of some runway which was in use most of the time. There, I saw my first American 777, and another one, and another one, and a.... Also my first Virgin a340 and a Sri Lankan 340. Landing too late to make pictures was the Hong Kong Cathay 744 (the new one) But I shot that one later that day from the sky. Also when we taxied, the Virgin A346 rolled by, but I couldn't take a pic (wrong side of the aircraft)...
Heathrow itself is quite a mess, but I am sure there are reasons for it.
will be back someday!
