I remember when the 747 and the L-1011 were the biggest planes on the runways! Loved them. I also remember when the Concorde came for a visit to my hometown, sometime in the mid-70s (I think they were trying to sell the concept, and were taking the plane on a goodwill tour of sorts). Loud. But, oh, what a lovely, lovely sight, especially to the eyes of a child. I will never forget that.
