Damm Autochecker. Of course i mean roost, but of course they did a bit of roasting as well.
To be honest, too much drama, not enough factual (in fact quite a bit of it didn't happen like that at all). 10 out of 10 for showing Lindermann as a major hindrance, but that was at the start of the project. He was on the Tizard committee when it formed (he was put on it to keep Churchill quiet), but did nothing but rubbish RDF in an attempt get funding for his own pet projects (Aerial Minefields and Infrared detection). The other members of the committee bar Tizard, Lindermann and Rowe (who was the Secretary) resigned which allowed Tizard to disband and reform it without Lindermann. By the time this happened Watson Watt's team had already built a working system at Orfordness with a range of 80 miles and were well on the way to solving the problems that gave them the real headaches (bearing and height finding). As for bouncing signals of the ionosphere to increase range, totally boll@cks. Reflections off the ionosphere were a major problem with CH (it caused clutter) that required some careful design in radar operating parameters to overcome. By the end of 1935 the Air Ministry were totally committed on building the first 5 CH Stations starting at Bawdsey. As for the end part in the Ops room with an Operational Trial on the eve of the start the Battle of Britain? The first five stations were fully operational by the time of Munich, the command and control bugs were being ironed out (the filter room had just been installed at Bentley Priory and declared operational) and one of the first tracks ever plotted by the RAF C&R network was Chamberlain's aircraft outbound to Germany for his 'peace in our time; meeting with Adolf. Plenty of real operational radar controlled combat intercepts had been done before July 1940. Watson Watt wasn't cut out of anything, he became the director of Bawdsey and in 1938 was promoted to control development of the wider range of radio systems at the Air Ministry.
Ok, its a television drama designed for people that don't know the subject and technical issues don't make good drama and in that light, it does highlight what was done. Though the Telephone in the bucket of water bit wasn't done by Watson Watt, it was favorite of R V Jones. I think Peter Ustinov's 1946 film based on what TRE did from 1938 - 1945 is better, even with its 1940's stereotypes because most of what was shown on film actually happened.
