Colin Dorrance was one of the first and youngest police officers on the scene when a terrorist bomb blew up Pan Am flight 103 in Lockerbie Scotland on December 21, 1988.
"It was a complete horrific scene for everyone to have to deal with," siad Dorrance.
Almost 30 years later, Dorrence and other first responders are cycling that distance from Lockerbie to Syracuse, all 3,238 miles.
"We wanted to complete the journey that those on the plane couldn't complete."
Checking in with victims families along the way.
"That has been so touching, so supportive. That was the whole intention that that was what we wanted to demonstrate we were with them 30 years ago and we will never forget them."
Bikers will start their final leg of their journey from Anna Marie Miazga's home in Marcy. Anna Marie is the mother of Suzanne, one of the victims of the bombing.
They're scheduled to arrive in Syracuse on Thursday afternoon before returning to Scotland over the weekend.
