.... "Some myths remain persistent no matter how much they are proven to be false."
"No, this is not a "Tom Cooper discovery": the story of the delivery and assembly of Mirages of French manufacture in Israel was published in the American magazine Wings, in 2001, in an interview with the American aircraft designer Gene Salvay. Salvay worked for North American since World War II and participated in the creation of types such as B-25, F-86, F-100, etc. In the mid-1960s (after the cancellation of the XF-108 Rapier interceptor), North American was purchased by Rockwell, originally a company specializing in the manufacture of auto spare parts, which meanwhile had strong intentions to expand, so also launched the production of auto spare parts in Israel.
In 1970, Salvay was one of the leading aircraft designers in the United States. Rockwell therefore sent him to Israel to help install the General Electric J-79 engine on the Mirage’s fuselage.
This is how he witnessed the delivery and assembly of the Mirage 5J by American technicians at IAI. In fact, this is how Salvay then designed the Kfir,
with much help from Lockheed and Dassault, before returning to the US. He designed the B-1 bomber (among others). The rest of the story was unearthed by Albert Grandolini in France, while David Lednicer took the photo attached below, which shows the plaque of the maker of the first Mirage 5J (exhibited at the Israel Air Force Museum in Israel)."
"Unsurprisingly, even the "most authoritative investigators" still insist that "only the first Nesher" was "made in France". In fact, the story of Dassault’s involvement with the IAI was just beginning: in South Africa it is a "public secret" how many parts of 'IAI Kfir' were acquired to obtain the Cheetah fighters in the 1980s and 1990s,
which were also "made in France".

This is a simple matter of logic and minimum knowledge of aeronautics. No one makes structural changes without the knowledge and support of the manufacturer to have his previous data of the structural resistance tests and after exaustive tests in wind tunnels. Everything else is mythology and propaganda.
