The film “Devotion” re- ignited efforts to repatriate the remains of Jesse LeRoy Brown, America’s first Black Navy pilot, who died in 1950 after having to crash land his damaged plane during the Korean War.

Fred Smith, the founder of Memphis-based FedEx, financed the film about Mr. Brown because he thought Mr. Brown deserved wider recognition, a feeling his surviving relatives share, and lobbied the Trump administration to support the search efforts after consulting with Mr. Brown’s daughter, Pamela.

“I’m still determined to try to get Jesse Brown home and put him where he ought to be in Arlington (National Cemetery),” Mr. Smith said. “Among the other heroes of the republic next to his wingman, Tom Hudner.”

Mr. Smith’s daughters, Rachel and Molly, who produced the film, met members of Mr. Brown’s family at the 2018 funeral of Mr. Hudner, who received the Medal of Honor after attempting to rescue Mr. Brown. Mr. Hudner returned to North Korea in 2013 in an attempt to locate Mr. Brown’s remains, but was unsuccessful.

Jessica Knight Henry, Mr. Brown’s granddaughter, said attending Mr. Hudner’s funeral at Arlington solidified her grandmother’s desire to have her husband’s remains interred in Arlington.

“He’s never had a full sort of burial with the pomp and circumstance that we think is worthy of what his contribution is to this country” Ms. Knight Henry said, speaking from Washington.

Mr. Brown grew up in Mississippi, the son of sharecroppers, and succeeded in qualifying to be a pilot in the Navy, despite his training officer refusing to pin on his wings — just one of many racist insults and hurdles he overcame.

Mr. Smith has donated proceeds from “Devotion”, in part, to endow a new scholarship fund, the Brown Hudner Navy Scholarship Foundation, for the children of Navy service members pursuing studies in STEM.

“Mr. Smith spent an incredible amount of money imaging the area where we think that my grandfather’s remains are,” said Ms. Knight Henry, adding that her family has worked with different agencies and groups to maximize any potential opportunity to get answers.

More than 7,500 American military personnel remain unaccounted for in the Korean War, according to the government agency that tracks prisoners of war and those missing in action.
