Mystery of 'Flying Tiger' flight which went missing with 107 people on board still unsolved 60 years later

It's been 60 years since an aircraft with 107 people on board went missing without a trace.

The Flying Tiger Line Flight 739 was en route to Saigon as part of a secret mission during the Vietnam War.

A private citizen, Morrill Worcester, decided to erect a monument to honour the names of those lost on his land in Columbia Falls, Maine.

“When I first heard the story about this mission, I was shocked to learn that nothing has been done for these families,” said Worcester.

“I said that day, that we would do something to make sure these people are honoured and remembered, and to hopefully give some closure to these families."

This is the only monument that currently pays its respects to those lost. However, the families of those that disappeared are trying to right that.

“They’re being pushed aside to be forgotten. That’s incomprehensible. They can’t be forgotten.”

Jennifer Kirk goes on to explain how her uncle was chosen by 35th US president John F. Kennedy to be on the special mission as 'part of an elite team'.

In an interview with Local 4 News Detroit, Jennifer shares the heartbreaking story of how her uncle was reluctant to leave for the mission and kept coming back to hug his family before saying he had to go and didn't know when he would be back.

Little did they know that would be the last time they would see each other.

Jennifer went on to explain how, for the sergeant's mother, the news of the missing plane was 'too much'.

"She'd never accepted it. For the full time, from that moment until she passed, she always swore that he was coming home," Jennifer said.
