Island Images - The Isle of Man in Pictures
Probably the best radar system Ronaldsway has been equipped with (out of around six). The Plessey Watchman with Cossor SSR initially installed in 1995 (SSR 1998) and operational within 2 months.  Finally replaced in 2017 by the rather poorly performing system on the hill behind which took 6 years to become operational.
