I'm sure fellow pPruners will know that the Whirlwind was designed by W E Petter, who went on to design the Folland Gnat and two English Electric products, the Canberra and the Lightning. Those were the days ...
Chug, the other example of lateral thinking was on the Tsetse Mosquito, where de Havilland turned to the Molins cigarette packaging company to design the feed for its monster cannon which thereafter was known as the Molins gun. And very well it worked, by all accounts, until its replacement by RP. I suppose the gun round resembles a giant cigarette, and both products were hazardous to health, even though the ciggies take longer to do the job.
