Cole Holzer, a 7-year-old from Casselton, North Dakota lost a very special t-shirt that belonged to his father on a Delta flight from Fargo to San Diego. Cole's father died two years ago when he was hanging Christmas lights and fell, reported WDAY an ABC affiliate.

Cole Nike t-shirt once belonged to his father. Good Morning America reported that Cole left the shirt behind on a plane and didn't realize until they were driving away.

"I started to cry a little bit," Cole said to WDAY.

Good Morning America reported that a Delta employee went above and beyond to get the t-shirt back, according to a letter written to the airline by a family friend.

"Kelly Cruchet's letter details the phone call to the Delta 800 number and how that employee called all over the San Diego airport looking for the shirt. The plane the Holzers had been on had just left San Diego for Minneapolis. Eventually, Cruchet got in touch with Delta's Lost & Found at the San Diego airport. Vicki Katseanes, another Delta employee, said she would check with the cleaning crew," reported  Good Morning America.

Cruchet also sent out an email and posted something on Facebook hoping that she could find someone that would meet the plane in Minneapolis and see if the t-shirt was still on it. Delta pilot Mike McLean saw the post and said he would try and contact ground control to see if they could get in touch with them.

"I then got the heartbreaking call from Vicki that the cleaning crew never found it, I thanked her and we ended the call," Cruchet's letter said according to GMA. "A short time later she called back and said she had been in contact with Alfredo, a Delta ramp supervisor. They wanted to confirm their names to confirm their flight and rows and said they were going to start looking through garbage!"

Thirty minutes later the shirt was found and Cole and his mother went back to the airport to pick up the shirt.

Delta  Spokesperson Michael Thomas told ABC News, "Efforts made to reunite this very special shirt with this customer and his family is another fantastic example of Delta people going above and beyond for our customers and truly speaks to the culture of our dedicated employees."
