I have 3 heart attacks with each ISS launch: Rocket program head

Talking about International Space Station (ISS) rocket launches, US aerospace company Northrop Grumman's rocket program head Kurt Eberly has said, "I have about three heart attacks each launch countdown." After the rocket was launched to ISS last week, Eberly added, "I think it's five...heart attacks. I lost even more hair. But now it's an incredible feeling of relief and happiness."
