A few months ago I was on the 1000th MD80 ever built, N960AS. I was also on one of its initial flights back in '92. Upon delivery to AS, the aircraft was adorned with a plaque of its significance on the wall opposite the lavatory between the galley and 1D.
I was sitting in 1A and noticed four holes in the wall, indicating the plaque had been removed. It was a bit sad to realize that the aircraft was being readied for sale. Whoever has the plaque now, has got themselves a significant piece of McDonnell Douglas history! Where is that plaque?
