door and attacked the pilot crew. and the final moments of united flight 693. it s all straight ahead on a second look. hello everyone i m frank somerville. last week a man tried to get into the cockpit of an airliners bound for san francisco. he wasn t able though to get past the reenforced door and flight attendants and other passengers eventually subdued him. such attacks on airlines and cockpits are not a new thing nearly a century ago. a dispondent man with a shotgun went into the cockpit killing the pilot and co-pilot. bringing the plane crashing down. reporter: it was may seven, 1964 just before seven 7:00 in the morning, the flight was on its way to reno from sfo. i was just getting ready to pick the kids from the school. then i heard a loud whine. i saw this big explosion. i said oh my god it s a plane crash. reporter: rescue crews arrived but there was no one to rescue. all passengers were killed including pilot ernie clark. ernie was the best. everyone
