LONGMONT, Colo. — The windows shook as dynamite aboard an airplane exploded over Conrad Hopp’s family farm 70 years ago. Hopp, then 18 years old, saw a ball of fire streak across the night sky and rushed with his brother toward the burning wreckage, dodging objects that turned out to be the bodies of victims of the first confirmed case of sabotage against a commercial U.S. airliner.
Hundreds of miles away, Marian Poeppelmeyer’s mother was at home in Pennsylvania when she learned her husband was among the 44 people killed in the bombing. Hopp and Poeppelmeyer, who recently forged a friendship through their shared trauma, plan to be together as they dedicate the first memorial honoring the victims on the 70th anniversary of the tragedy.
The United Airlines flight had taken off a few minutes late after a layover in Denver on its way to Portland, Oregon, leading to a bomb planted by Jack Gilbert Graham, who had personal grievances against his mother. Graham confessed to putting 25 sticks of dynamite in her luggage, intending to cover his tracks by having the plane explode over remote mountains. However, the flight’s delay caused the explosion to occur over beet fields north of the city, enabling investigators to piece together the wreckage and interview eyewitnesses.
In the aftermath, while Hopp helped recover and protect bodies, Poeppelmeyer’s family remained silent about her father’s death, which contributed to her own struggles to find closure. Through their recent connection, the two now remember not only the tragedy but also the humanity of the victims and the survivors left behind, creating a beautiful bond in their shared narrative.
