Lisa Beamer, the widow of Sept. 11 United Airlines flight 93 hero Todd Beamer, gave birth to his daughter — their third child — on Wednesday, a healthy baby girl, the Associated Press reported. She was named Morgan, taken from her late father’s middle name. The baby weighed 7 pounds and was 21 inches tall, and is sister to the couple’s two young sons, Drew and David. Todd Beamer, 32, is credited with shouting, “Let’s roll!” to his fellow passengers when it came to facing down the hijackers who overtook the flight, which ultimately crashed in a field in western Pennsylvania, killing all 44 of those onboard. Beamer was among several passengers who called relatives or authorities from the flight, alerting them to the hijacking and saying they were planning to fight back. Among Beamer’s last words to a GTE operator before he dropped his phone were: “Let’s roll!” Flight 93 left Newark en route to San Francisco and was the only hijacked plane that day that did not crash into a landmark and take lives on the ground. Authorities believe the hijackers were steering it toward Washington when passengers brought a halt to their plans. A few days after the tragedy, Lisa Beamer recalled that “Are you guys ready? Let’s roll!” was a favorite expression of Todd’s. “Some people live their whole lives, long lives, without having left anything behind,” she said at the time. “My sons will be told their whole lives that their father was a hero, that he saved lives. It’s a great legacy for a father to leave his children.” She also established the Beamer Foundation to assist other children who lost parents on flight 93. Her family will not receive assistance from the fund.
