A soldier has watched the birth of his daughter via the FaceTime app from the floor of an airport in Dallas, Texas after his flight to Brandon, Mississippi was delayed.

The image of Specialist Brooks Lindsey sitting on the ground of Dallas-Fort Worth airport, glued to his phone was shared to Facebook by fellow passenger Tracey Dover and quickly took off on social media.

“This Army soldier was on my delayed flight home yesterday to MS,” Ms Dover wrote.

“He had to watch the birth of his daughter on FaceTime. He was crying and our hearts were breaking.

“We all gave him space. When we heard the baby cry, we all rejoiced for him.

“I wanted to share this because I never want us to forget about our soldiers who serve us everyday and the sacrifices they make.”

The image has been shared more than 120,000 times on Facebook and Twitter.

The new dad was congratulated and thanked by people around the world.

The photo also prompted others to share their own experiences of the personal sacrifices made by defence personnel.

Lila Smith Arquitt commented that she was a military wife for 20 years and could relate.

“My heart breaks for this soldier but so glad he was able to watch the birth on line (sic)!” she wrote.

“My husband missed many special events that happened during our 20 years of Military service in the United States Army! Congratulations to this soldier and his family on the birth of his child.”

Another women said her son, who is in the Navy, had also used the video call app to be part of the birth of his firstborn.

“My firstborn son is a Marine and he missed the birth of his firstborn in January. Although it was sad, we are so grateful for technology and we were able to FaceTime,” Renea Walker said.

I completely understand & hope he gets to see his child soon. My dad was in Korea when I was born, I didn't get to meet him until I was almost a year old. I treasure my father & thank him for his service & sacrifice often.

Mr Lindsey’s wife Haley took to social media to thank people for their support.

“I really hope it gives other military families hope for getting their loved ones home in an emergency or other life change,” Ms Lindsey said.

“It may have not went exactly how we planned, but it is absolutely perfect the way it is! Thank you Tracy Dover for sharing this moment with us and everyone!”
