This week in Britain
Half a life time ago ABC Austalia used to screen a program fronted by a Pom with a plum in her mouth called 'This week in Britain'. One memorable episode featured a Wessex with microwaves piped up the rotor mast to rotor blades modified as antennas. I recall a detailed image of London on a CRT in which the Thames was clearly visible.
How you could fiddle with a helo power plant to the extent that the main drive shaft out of the gearbox became a waveguide & still keep the machine air worthy is just awesom I reckon.
