Proskow said the airport announced over the intercom that Knight was being returned home, prompting the "entire terminal" to watch his arrival.
Roy Knight Jr. was shot down in May 1967 while pursuing a target on the Ho Chi Minh Trail in Laos.
His son, Captain Bryan Knight, was five years old when he last saw his father.
A joint US-Laotian team recovered remains from the crash site earlier this year and they were identifed as Major Knight's through dental records, according to the Pentagon's Defense POW/MIA Accounting Agency.
"As we were walking back to the auto my mother was was just sobbing and that scared me", Knight said.
Once the younger Knight learned that his father's remains had been found, he launched the process of repatriating them.

His son, Bryan Knight now a Southwest airlines captain had been able to make the final leg of the journey, flying his father into the airport, where the plane was met with a water cannon salute before his father was given full military honors. The flight landed at Dallas Love Field.
On Thursday, his flight home to Dallas aboard a Southwest Airline flight inspired an impromptu moment of silence in the terminal.
"When I first got the call, it was nearly surreal", Bryan Knight told Southwest Airlines.
Proskow concluded, "On May 19, 1967, Maj".
"Airports rarely see moments of quiet-but for a few brief minutes, Dallas Love Field fell absolutely silent", he wrote.
He was accepted for pilot training in 1957, going on to serve in Germany and France as a fighter pilot. Onlookers stood silently at the window, some wiping away tears. He was initially listed as Missing in Action until being declared Killed in Action in 1974.
"How many people would ever have the opportunity to do this", Knight said.
A funeral service will be held for Col. Knight in Weatherford, Texas, on Saturday, his obituary states. He and his wife, Patricia, had three children while he served in the military.
