I have just started reading this book and immediately came across an anomaly.
It states that the Mig-21 was flown from Israel to the US in 1968 in the back of a C5 Galaxy and tested there between Feb and March of that year.
The problem is that the Galaxy only had its first flight in June of that year and was not operational until two years later.
That sort of thing makes one doubt the accuracy of all the following data.
