The official Flight 93 memorial flag, from Pennsylvania, was unfurled at the Pennsylvania State Capitol yesterday in recognition of the 24th anniversary of the 9/11 terror attacks. The flag was unfurled in the Capitol rotunda as bystanders sang “America the Beautiful.” It honors the passengers on United Flight 93 who fought back against terrorist hijackers, resulting in a crash in Shanksville, Somerset County, that killed everyone on board. The flag is back in Shanksville for today’s ceremonies, which begin at 9:45 this morning.
