> Sun Microsystems executive was killed in last week's terrorist attacks on New York's twin World Trade Center towers.

Philip Rosenzweig, an executive in Sun's Solaris software unit, was a passenger aboard American Airlines Flight 11.

"This has been a tragic event for our country, and has touched all of us at Sun," said Scott McNealy, Sun's chairman. "Our prayers and thoughts are with Phil's family and loved ones." Rosenzweig, 47, lived in Acton, Mass.

The plane on which Rosenzweig was a passenger struck the north tower, where Sun occupied the 25th and 26th floors with sales and support staff for its Wall Street customers.

On the plane with Rosenzweig were Daniel C. Lewin, co-founder and chief technology officer of Akamai Technologies. Lewin, 31, founded Akamai in 1998 with Massachusetts Institute of Technology professor Tom Leighton and a group of MIT scientists, while he was still a graduate student, and Edmund Glazer, 41, CFO of network infrastructure systems maker MRV Communications, was also on that flight, which was en route from Boston to Los Angeles.
