Two Veterans-One Dying Wish

I have never thought of asking for help from anyone. I am a disabled Army Vet (92M) and I have an amazing family and an amazing life. I am married with three children, and I have a lifetime of amazing memories.
My husband grew up without a father. The only memories he has is from 1981 when he was only 7 years old. After his parents separated, he lost any and all contact with his father.
Thirty five years later- and my stubborn use of social media- I have finally found him. I was honored to be able to hand him the phone one morning, and he spoke to his father after many years thinking that he'd long passed away.
His father is an Air Force veteran, from an era long before I existed. He is almost 80 years old, and we found out my husband has twin sisters and two more brothers.
I am asking for help, to bring this family together.
I am hoping that this year, we can get them here for Thanksgiving. I am afraid that waiting any longer could result in them never meeting. His father had a stroke last year, and I fear that time is running out.
This is the last of his family. We thought that after his mother passed in 2012 that he was just about out of family, and then we found him. He's in Arkansas and we are in Oregon. I just need help getting him here!
If anyone could find it in their heart to help out two fellow veterans, or just two families who are actually one, I would be eternally grateful.
Talk about a reason to be thankful... no better way to celebrate Thanksgiving. Any help would go a long way. This may be the only chance to make a dying dream come true for one man, and a lifelong dream come true for another.
