I guess what it tells me is to take more pix aboard todays 'modern' aircraft because they won't be around forever.
Not old enough to have travelled on a 707, but I have fond memories of my first transatlantic crossing on a Delta L1011-500 in the eighties. Not that long ago but sadly no more. Also travelled on one of Olympics 727's just a few weeks before it's final revenue flight in early 2000. The interior seemed very '70's' - bare flourescent tubes, threadbare seats and carpet, ashtrays (complete with ash). Had proper 'atmosphere' - certainley not an anonymous metal tube.
