On Friday, John Beaven will go about his regular business as vice president of ticket sales for the Warriors.Fourteen years ago, Beaven was in Australia when the evening television show was interrupted by images of the World Trade Center being hit."There's a good chance your father was on one of those planes," she said.Alan Beaven, a well-respected environmental lawyer, was on Flight 93, the plane that was downed in Pennsylvania.Weeks after Sept. 11, the Warriors presented the Alan Beaven Family Fund with a $25,000 check.The gesture would have profound implications for Beaven.After graduating and having his dreams of a major-league career derail in the minors, he was lost.Fourteen years and a NBA championship later, he has risen to vice president.Some might say he has the easiest job in sports right now, with a ticket waiting list of 16,000.Ann Killion is a San Francisco Chronicle columnist.
