He Was the Key to a Top-Secret Missile Program. Then He Walked Out of His Office—and Was Never Seen Again.

Here’s what you’ll learn when you read this story:Egypt relied on a group of former Nazi scientists to spearhead its missile program. Caught in a fierce crossfire between Israel, Egypt, and West Germany, one Nazi rocket scientist disappeared into thin air—crippling a rocket program and stumping historians for decades. Feeling threatened by Egypt, Israel pressed West Germany to stop the former Nazi scientists, given that the scientists were German citizens. Sirrs suggests West German intelligence may have directly assisted agents from Mossad—an Israeli intelligence organization—in targeting the missile program. While many scientists left the team, Krug continued to work on the missile program from his office in Munich.
