It never arrived, and no one went looking for the doomed aircraft or the eight men on board because military officials had no way of pinpointing where it went down.
All signs of the mission were lost until 2006, when a hiker in northeast India spotted a wing and panel sign with the plane's name inscribed, "Hot as Hell."
It wasn't until 2015 that the US Defense Department investigated the crash site and found the remains of 1st Lt. Robert Eugene Oxford.
"We were ecstatic that Eugene was found, but we feel guilty there are seven other men on that mountain top," said Merrill Roan, the wife of Oxford's nephew. "So we are honouring the other seven. ... We have to honour them as well, because they may never get any closure."

Oxford's family didn't know the wreckage had been found until 2007 when Merrill Roan saw a message on a genealogy website from a relative of another service member on the aircraft. That relative wanted help persuading military officials to investigate the crash site.
Duus' agency confirmed the crash site correlated with the missing aircraft in 2008. But harmful weather coupled with access issues and security delayed recovery operation efforts until late 2015, Duus said.
Roan said the family was "shocked and excited" when they heard the news.
Duus said Oxford is one of 74 veterans who have been identified so far this year. She said all service members have been returned to the US for identification before the family is notified and the service member is provided a funeral with honours.
Eighty service members were identified in 2015, and that number more than doubled with 164 the following year, Duus said.
The Missing in Action Agency website says there are more than 86,000 Americans still missing abroad from World War II, the Korean War and the Vietnam War. Advancements in DNA testing technology and partnerships with other nations has helped find and identify more missing service members than ever, Duus said.
A State Patrol escort will guide a hearse carrying Oxford's casket 50 miles south on Interstate 75 from Hartsfield-Jackson Atlanta International Airport to the funeral home. A funeral will be held Saturday in a school auditorium, the biggest venue in town, Moody said.
"It's just a huge historical event for our little town," Moody said. "The phone constantly rings from people wanting information."
