United Flight 629 Memorial

In late 2025, the Museum will host a ceremony to remember the victims of the tragic United Airlines Flight 629 disaster, the first act of aircraft sabotage in the US. This event will be dedicated to the families and loved ones of those who perished when the Douglas DC-6B, registration N37559, was destroyed by a dynamite bomb on November 1, 1955. The Museum is committed to preserving the memory of this horrific event and providing support to the families of the victims. By remembering the events of United Airlines Flight 629, we honor the 44 lives lost and reaffirm our commitment to aviation safety and the role of law enforcement in investigations. This tragedy serves as a stark reminder of the importance of vigilance and security in the aviation industry.

The Denver Police Museum is honored that the Rocky Mountain Chapter of the Society of Former Special Agents of the FBI is joining us to help facilitate the activities planned for October 31 through November 1, 2025. Miles Gooderham, Chairman of the Society was kind enough to allow representatives of the museum an opportunity to share the plans honoring both the law enforcement response to the tragedy, and the 44 victims. Thanks to the work of Denver Police Museum volunteer Jeff Burke on Ancestry.com, we have successfully located the family of Roy Moore, the lead agent, who successfully got the bomber to confess. Agent Moore was later sent by J Edgar Hoover to handle to civil rights issues that were going on in Mississippi. We are delighted that Agent Moore’s family will be joining us next fall for the memorial activities.

The Denver Police Museum has also contacted FBI agent Don Sebasta’s family. Agents Sebasta and Moore facilitated John Gilbert Graham’s confession placing bomb on UA 629. Agent Sebasta was subsequently a key figure in solving the Coors kidnapping and murder in 1960. Both families will be attending the event October 31 and November 1, 2025.
