For six months, a petite brunette calling herself “Lena Rigon” quietly appeared at a French airfield and learned to fly helicopters. Her instructors had no idea why. Her real name was Nadine Vaujour. And she was learning so she could fly into a Paris prison and steal her husband back. Michel Vaujour was a convicted armed robber and notorious escape artist serving an 18-year sentence at La Santé Prison. He had already escaped custody several times. But this plan required something neither prison walls nor guards could easily stop. A helicopter. Nadine trained until she earned her pilot's license. She became a regular customer at a helicopter rental company, returning again and again until renting an aircraft no longer seemed suspicious. Then, on May 26, 1986, she was ready. At approximately 10:40 that morning, a white Alouette II suddenly appeared above La Santé. Nadine brought it into a hover over the prison. Below, Michel made his move. With another prisoner helping him, he reached the roof. Nadine held the helicopter steady above one of Paris's most secure prisons while Michel climbed aboard. Then she pulled away. Within minutes, the prison was behind them. Nadine landed on a soccer field near Paris's university district, abandoned the helicopter and disappeared with Michel. France launched a massive manhunt. The escape worked. For four months. In September, Michel was caught after a failed Paris bank robbery ended in gunfire. He was shot in the head and critically wounded. Nadine was arrested shortly afterward. Their extraordinary escape was over. Years later, even their marriage would end. But for one morning in 1986, Nadine Vaujour had done exactly what she had spent months secretly preparing to do. She learned to fly a helicopter for one reason. Then she flew straight into a prison and took her husband out through the sky.
