Mr Noritake,
Remember that the early Migs would have been nothing if the British Government had not given the Soviets our jet angine technology.
Even up to recent years the Russian Avaition Industry has lagged behind with the latest computer technology. However, once they GAIN the information they are quick to put it to good use.
The Western Airforces used to laugh at those who only achieved 150 hrs a year and did much with simulation. How times have changed.
There is still no doubt in my mind that in 1970 - 1982 the Phantom FGR2 was the most capable fighter aircraft in the Central Region.
