And, of course, add to this that pylons are spindly and what ? 60 feet tall
maybe ?

Over 130 feet for a typical 400 kV pylon. Nearer 100ft in rural areas.
Slightly lower profile towers have been used more recently.

Ground clearance is a minimum of 25ft at 400kV and nearer 40ft in most cases

The tallest UK towers are the ones across the Thames and the Severn 623ft &
488ft respectively.
