DENVER (CBS4) – Notes were placed at the memorial in Shanksville, Penn. where United Flight 93 crashed on Sept. 11. That’s the flight passengers and crew members brought down before it reached its intended target. Forty people died, including Colorado pilot Jason Dahl.

CBS’s Kathy Walsh talked Dahl’s widow, Sandy Dahl. She said she’s relieved.

Sandy said she has suffered post traumatic stress disorder following Jason’s death. That day changed her life forever. She’s glad that after nearly 10 years Osama bin Laden has finally been stopped.

“I didn’t sleep much last night,” she said.

Sandy said she was shocked to learn bin Laden was dead. It was news she’d hoped for ever since Jason died.

“I was afraid it would be a picture of him on his death bed being fanned and fed grapes and all of his wives and children around,” Sandy said. “I was afraid that would be the ending that he would die a hero in his people’s eyes, but he died in a way I think is appropriate.”

Sandy calls Jason a hero and bin Laden a terrible coward — sheer evil.

“He trained people to do hateful things that he didn’t do himself.”

She’s happy the al Qaeda leader can’t hurt anyone else, but she’s still sad.

“It doesn’t make it any easier because it doesn’t bring Jason back.”

She’s still worried about terrorism.

“It doesn’t make it any easier because I know there are more out there ready to pick up where he left off.”

Sandy is especially concerned about the upcoming 10 year anniversary of Sept. 11.

“(We should be) praying for our safety, praying for our president’s, praying for our military everyday and being diligent. We need to not just relax and forget this happened because that’s what they wait for.”

Sandy devotes much of her time these days to the Cpt. Jason Dahl Scholarship Fund to help students pay for commercial flight school. She said on the Sept. 11 anniversary this year she will be holding a fundraiser in Colorado. She will not go to the scene of the crash in Pennsylvania.
