I can't find the facts to prove it, but I am certain that there were never 5 concordes at MAN simultaneously, especially on pier B. At the back of my mind there may have been either 2 at once, or 2 on the same day but not the same time, but that is all. The concordesst website refers to a picture of 5 BA concordes taken the day they retired from service - I suspect that may be the only time 5 were lined up together anywhere in the world!
