EUGENE, Ore. -- Donald Gibson was just 22-years-old when he joined the U.S. Air Force and was stationed at the RAF Mildenhall military base in Suffolk, England.
He met his future wife, Christine Waterfall, and they were married in 1989. Later that year, their son Craig was born.
"I remember his birthday like it was yesterday. He was born Friday the 13th at 7:10 a.m.," Gibson said.
Gibson's military career soon ended, and Gibson says he had visa issues so he had to move back to the United States. Gibson left England in 1991.
"I was scared to death. I had no idea of a way to support her and a family in that country," said Gibson.
Gibson kept in touch through letters and phone calls, but after time, they lost touch.
Both Gibson and Craig - who carries the last name Waterfall - sidy they spent the next two decades trying to find eachother.
"I've paid for services, you know, those paid deals to locate friends and family. Never had any luck," said Gibson.
No luck until Gibson was browsing through Facebook in mid-June and found Waterfall's name and photo.
"There was no question in my mind. I knew who it was," said Gibson.
After exchanging Facebook messages, the father and son Skyped for the first time on Father's Day.
"His first words were 'hi Dad, happy father's day," said Gibson.
Waterfall is now 23 years old and a hair dresser in Peterborough, England. He said he never lost hope of finding his dad. "I kind of thought the only way I'd find him is going to America," said Waterfall.
"You get to the point where you put your hopes up and then you get down when you don't find anything," said Waterfall in a Skype interview Tuesday.
Gibson and Waterfall have been in contact every day since Father's Day, but they want to see each other in person.
"I'd say I love him and I don't think i've told him that yet and he tells me everyday," said Waterfall.
Gibson said throughout it all, he and his wife both loved eachother. Gibson said they plan on re-marrying.
Gibson said he plans on moving to England to live with his only son. He is submitting his visa paperwork, but he first needs to find the financial means to move to England.
"I would live in a cardboard box if I could just be with him," said Gibson.
