A group of scientists that were hired by the FBI to look into the mysterious case of D.B. Cooper believe they have uncovered new evidence. The believe that he may have had connections to the aerospace industry.
The group has found particles left behind on his clip on tie that include cerium, strontium sulfide and pure titanium. These elements were not widely used in 1971 which the time of Cooper’s famous jump from an airplane.
These elements were used though in the 1960’s and 1970’s by Boeing’s high-tech supersonic transport plane which was being developed during this same time period.
So was DB Cooper a Boeing employee or a contractor? That would explain how these rare elements were found on his tie. The group is also asking for further help from the public if they have further knowledge of those specific elements. They may have another use or be associated with each other for another process or in another environment.
