The wife of the co-pilot of United Airlines Flight 93 that crashed in Pennsylvania during the 2001 terrorist attacks will be the guest speaker during a 9/11 remembrance ceremony at 10 a.m. Friday at Patriots Point in the Yorktown theater.

Melodie Homer, wife of co-pilot LeRoy Homer, wrote a book titled, “From Where I Stand,” which chronicles the events that day and the life she has come to know since losing her husband.

Flight 93 had 33 passengers and seven crew members on board when it crashed near Shanksville, Pa., after terrorists hijacked the plane and passengers fought back to prevent the jet from reaching a target in Washington, D.C.

“Twelve years later and the pain and hurt from that terrible day is still deep for America; but nobody feels it like those who lost husbands, wives, children, grandchildren and those they love most,” Patriots Point Executive Director Mac Burdette said. “Melodie Homer offers assurance that through grief we can still persevere.”

Following Homer’s remarks, a panel discussion will take place on the changes in safety in airports and the air since Sept. 11, 2001. Members of the panel are Homer; Jim Peacher, manager of airport security for the Charleston County Aviation Authority; and Bill New, deputy director of the Charleston County Aviation Authority.

The ceremony will conclude with a wreath-laying on Charleston Harbor. Admission to the museum will be free from 9:30 a.m. to 10:30 a.m. The $5 parking fee will still apply.
