I have an image of concorde at Hatfield from when I went to an airshow with my Grandfather, I remember it did a touch and go then 1 circuit, and as it came over the field it slowed as much as it could, then bowed to the crowd and went back to London.
In the back of my mind I seem to remember it either set off from Luton or returned to Luton with BAE Hatfield staff.
