Just to add something....... the 'Jet' in question, (Daily Mail, Later Version) has been pictorially modified, quite right in my view. It has had the Serial and Sqn markings removed. But, that is all. Despite the quotes from earlier posters, it is a recent picture, taken with proper wpns.
If you don't know what I mean, then it doesn't matter. But it is all 'open source', and has been for years.
I am quite suprised, that some of the better 'Spotters', haven't made a connection yet...... ho hum, I guess the trees hide the forrest eh?
