Flight Lessons

The problem would be in maintaining the furrow, wind and water would fill it
in in a short period of time and it would not be detectable with the MK1
eyeball from the air within a period of months? years?.

I live on salt water, with extensive mud flats. I walk out at low tide
to set a mooring etc. My footprints are visible for at least a week,
maybe two. That would be the low end of "Look on my works, Ye Mighty,
and despair!"

On the other hand, I've been told that the scorched earth where
gliders burned at Arnhem? in 1944 are still visible from the air. And
I have walked with great comfort along the former logging railroads in
the White Mountains, the railroads having disappeared 80 years
earlier.

all the best -- Dan Ford
