"Building upon previous Polish work"
The British like to overlook the fact that without the Polish mathematicians and pilots, the inhabitants of the British Isles would quite probably now be speaking German. The way the Polish are treated by the British is disgusting. The two countries should have had a long lasting friendship after the war due to their combined efforts that resulted in the defeat of the Nazis, but no, Britain left the Poles to the mercy of the Russians. So much for gratitude.
