F1 champion and aviation entrepreneur Niki Lauda dies at 70

VIENNA – Three-time Formula One world champion Niki Lauda, who won two of his titles after a horrific crash that left him with serious burns and went on to become a prominent figure in the aviation industry, has died. He was 70.

The Austria Press Agency reported Lauda's family saying in a statement he "passed away peacefully" on Monday. Walter Klepetko, a doctor who carried out a lung transplant on Lauda last year, said Tuesday: "Niki Lauda has died. I have to confirm that."

Lauda twice underwent kidney transplants, receiving an organ donated by his brother in 1997 and a kidney donated by his girlfriend in 2005.

In August last year, he underwent a lung transplant that the Vienna General Hospital said was made necessary by a "serious lung illness."
