Book excerpt: Israeli delta fighters pilots have been credited with almost 300 kills between 1966 and 1974, and dozens of them became aces. The Israeli aerial kill exchange rate and overall air-to-air performance was phenomenal. Although the Israeli pilots were flying Mach 2 fighters, they lacked any modern radar equipment and their MiG-21 flying opponents should have had a performance edge over them. This book details their most signifcant engagements, many of which were essentially World War 2 style dogfights fought with jet aircraft. Because neither side had the combat edge to disengage at will most engagements were a life and death struggle and the introduction of air-to-air missiles and the Israeli Nesher was to prove decisive in this theatre.
