remember the Aviaco DC-9 very well.
Also the Stirling Caravelle OY-SAH in May 78 I think. I have a photo somewhere.
You and I probably know each other other than by our monikers here then...
I'm sure I have a pic of OY SAH as well but on a 'basic' camera and with prints/negs still somewhere round my mother's place.
If you remember Dave W of that era he's currently putting up several scanned slides from seventies on FB every week .
