BJC, what's your point?
I wasn't the one that brought up them 'stealing' jet technology from the UK.
The US & British Empire supplied Russia with a lot of equipment during the war, a fact often played down by the former USSR. The Allies invaded Italy largely because of Soviet pressure to open a second front and to some extent the bombing campaign was driven by Soviet pressure (especially some of the late war attacks on Dresden etc). So while I'm not sure how the balance adds up, it certainly wasn't all one sided.
As for learning to speak German, we won the battle of Britain before the Soviets were fighting the Germans.;-)
However this is almost completely off topic. The Soviets I believe may have had their own candidate for inventor of the gas turbine jet engine.
KENAT, probably the least qualified checker you'll ever meet...
