Thank you to Colin Lourie for sending me this Google earth view looking down
on Edinburgh Airport. The horizontal black line that Colin has added to
this image shows roughly the line of the old A9 road. The airport boundary fence
ran immediately to the south of the road.
"There were a few cottages to the south of the
Almond beside Boathouse Bridge. These are shown by the black arrow in this
picture. Presumably the cottages were demolished when the
new runway was built."
