As much as I love Concorde, I think she looks totally stupid stuck out on the taxiway at LHR.
It looks like someone towed her there and dumped her, much like you would a stolen car.
I'm not sure I have any particular positive suggestions as to what I may do with her as I'm still mad she is not flying. But, it makes me very sad every time I taxi past and know that never again will I have the pleasure.
