The widow of the pilot of United Flight 93 says she's very troubled by the state of airline security. Flight 93 crashed in Pennsylvania after it was hijacked on Sept. 11, 2001.

Pilot Jason Dahl died in the crash. His wife Sandy Dahl is scheduled to watch the film "Flight 93" Tuesday evening at the White House with President and Mrs. Bush along with other families of those killed on Flight 93.

"I'm very excited and honored President Bush thinks enough of the families of United Flight 93 to invite us," Dahl said.

The 40 people on board, including her husband, fought back furiously against hijackers on that flight. Dahl said the film accurately portrays "all the chaos, how we were so unprepared." She says security is still not prepared the way it should be for another airline attack.

She said Tuesday she plans to bring up her concerns about airline security with the president.

"I can just tell you from being a flight attendant that things aren't the way they need them to be after 9-11," Dahl said.

Dahl questions the decision to allow small knives and scissors back on airplanes. She believes that the take-charge attitude captured in the movie "Flight 93" has not been matched by those in charged of airline security in Washington.

"There are incompetent screeners at the airport," she said. "These are my friends that work on these airplanes. Yes, it concerns me very much."
