My dad used to fly Edinburgh - London a few times each year in the 1960's. Was usually from Edinburgh (Vanguards) but I have a clear memory of him catching a flight from Dundee to Glasgow to connect with a London flight to see if that was a viable alternative. It would have been around 1967, it was from the grass strip and it was a Dove - I can remember the bubble. Can clearly see him walking out with a few other hardy souls and bouncing off down towards Invergowrie. I think there was some kind of portable building at the time for a "terminal".
