A couple of weeks ago I was on EZY from PMI to LTN and the routing took us over LHR at about FL290 (I think they said).
It was a fabulously clear afternoon and I got a magnificent bird's eye view of the place from an angle that I had not seen before.
What drew my eye was three Concordes sitting next to each in the sun, in perfect 'plan view'
From any angle and any altitude, she is the one.
