Re: Concrete Tornado
The code name was true. I worked at Ferranti in Edinburgh in 1981, helping out with developing the ground-mapping radar. All of the Ferranti internal project names began with the word Blue - "Blue Parrot", "Blue Tit", etc although the latter was always known as "Frigid Nipple" for obvious reasons.
The Tornadoes were known locally as the Blue Circle Airline (Portland Cement's trademark, in case anyone didn't know).
It wasn't a mix-up over sizes, though, just that the radar development lagged the airframe development, and having seen a Texas Instruments engineer wielding a sledge hammer during the project I think I know why.
