WATB is correct. In 1919, you could fly from Manchester's Alexandra Park Aerodrome to Blackpool, (South Shore Aerodrome), for a mere 9 Guineas.
Why Britain adopted the Guinea instead of the Pound Sterling I do not know...
WATB has declared
OPEN HOUSE, to no one's surprise...
Regarding the Hough End Aerodrome, I stand corrected, as the site is not completely without air traffic. On weekends, the site, (Hough End Playing Fields), hosts radio controlled model aircraft traffic. (See above photo, taken at Hough End Park) Nuff said.
