Many of us remember exactly where we were and what we were doing on this day, Sept. 11, in 2001.
It's been 15 years since terrorists attacked America, killing nearly 3,000 and wounding thousands more.
As you'll recall, Flight 93 never made it to its intended target in Washington D.C. because of passengers like Todd Beamer who fought back against the terrorists.
6 On Your Side talked with Beamer's father who was in the Treasure Valley Sunday.
Flight 93 was hijacked as part of the deadly attacks that brought down the World Trade Towers in New York and damaged the Pentagon in Virginia.
According to accounts of cell phone conversations from that day, Todd Beamer, along with three others on the plane came up with a plan to take the aircraft back from the hijackers. The plane was within 20 minutes from its suspected target, either the White House or the U.S. Capitol Building.
Todd Beamer and the other Americans on board were successful in doing so, crashing into an empty field in Shanksville, Pennsylvania
Beamer, who was a son, husband, father and software account manager, was on the phone with the FBI while hijackers had control of the plane. His watch was found in the wreckage. No one survived the crash.
Beamer's father, David, is good friend's with the senior pastor at Ten Mile Christian Church. He shared his 9/11 experience with the congregation.
David Beamer feels like people have forgotten that America was and still is a target.
"Are we safer now than we were 15 years later," he said. "It doesn't feel like it."
David Beamer, who lives in Ohio, reminded them that those who protect our freedoms should be thanked each and every day.
"Americans need to remember how blessed we are as a country... the freedom, the liberty we have to believe, speak, to celebrate, to work, to be safe and be secure," he concluded.
Todd Beamer was survived by his wife and their two sons who were three and one at the time of his death. Four months after the crash, his daughter was born.
