I didn't suggest it was unique. And I think there are a few thousand more since last Tuesday's Jubilee flypast.
I like it because I'm an enthusiastic supporter of Concorde, a big fan of the Reds and they rarely fly in formation.
The photograph I posted is good, but not as good as one I have on the wall in my Chambers (office). It's taken from above the formation, over the English countryside on a gin clear day. (They're also rare!
) The Concorde is G-BBDG, not in airline markings. I think it's Concorde 002.
Your photograph 'on brushed stainless steel and mounted on a shadow box frame' sounds very interesting - and is much more likely to be unique.
If you scan it and email the file to Helidrvr, I'm sure he'll be able to post it here.
