John Travolta’s directorial debut, “Propeller One-Way Night Coach,” holds special sentimental value for the actor.

Set to premiere on Apple TV+ on May 29, the movie follows a young airplane enthusiast as he embarks on a big trip in the skies.

Based on Travolta’s first flight as a child, and his 1997 book of the same name, “Propeller One-Way Night Coach” is a semi-autobiographical story for the 72-year-old, who makes his directorial debut with the movie. He also wrote and narrated the project.

While appearing on TODAY on May 20, Travolta reflected as to why his first flight was so transformative.

“My sister Ellen gave me a Christmas present in a glove box. It was a ticket. It was on National Airlines to fly from Newark to Philadelphia. I thought it was just a used ticket to play with and I was elated,” he told TODAY’s Willie Geist. “And then she said to me, ‘We’re going on Dec. 28.’”

When a young Travolta heard that he was going to be flying on an airplane, he was ecstatic.

“I almost went out of my body. I couldn’t believe that this would come true,” he said.

Travolta said the moment inspired him to dream big. That’s one of the messages he shares in the new movie.

“Just when (the young boy in the movie) thinks life couldn’t get better, it gets better,” he said. “And the whole movie is like an ascent of all these characters — not just the little boy — about resilience. And whatever happens, he looks at the glass half full and not half empty.”

Willie then pointed out that Travolta, who has extensive experience piloting planes, “started an entire life in aviation” due to the “seed that was planted” when he took his first flight.

“Exactly,” Travolta agreed.

While describing the movie, the actor said it’s an “homage to cinema.”

“It’s an homage to stars in the cinema, it’s an homage to the masterpieces of music of the mid-century and an homage to my life, which was inspired by my family. And my whole family’s in this movie, and without them, I’m not here,” he said.

Travolta continued, saying, “This is really a family and friends epic tale of what happens when you plant seeds early in life, what could happen.”
