SSD - Beautifully put. I saw XH558 at her final display at Cranfield in 93 (?), and I still get shivers up and down my spine thinking about it. I dearly wish my young son could see the beast fly...
But as for Concorde not being agile.. I got back in to LHR one evening last week, and while retrieving my car from Parking Express, she climbed out overhead from a 09L departure; burners plugged in, banking hard right and climbing away beautifully in the twilight. Granted she's not as agile as the Vulcan, but there's something about Concorde which makes her absolutely unique and very special. I just can't put it into words.
