A plaque that has been attached to a tree in Portsmouth, New Hampshire is missing. It honors First Officer Tom McGuinness, who was working aboard American Airlines Flight 11 on September 11, 2001, the first plane to be hijacked by terrorists that day.
His widow planted the maple tree and put up the plaque by Portsmouth’s Federal Building in 2002.
The Portsmouth Herald reports that a bolt that held the plaque in place has been cut.
