The detectives bring Betty Joe to the station and tell her they know she was given ration books from her brother who worked at a military incinerator. She remembers when Lynn gave another pilot named Edna a pep talk. Lynn said her father worked on a B-17 where he was killed. Betty Joe says hearing Lynn made her reconsider and stop selling the ration books. Betty Joe says she regrets that Lynn didn't fly the jet. She says a pilot named Louise Patterson was the first woman to fly it.

Valens and Rush meet with Louise. They ask her if she wanted to get rid of Lynn since she was her competition to fly the jet. Louise remembers when Edna died after her plane crashed. Lynn said she can't believe Edna crashed since she instructed her. Afterwards, the pilots bonded while singing the Airforce song.

Valens tells Stillman that the army reports Edna's plane crashed due to a mechanical failure. Valens says he has doubts since the maintenance logs show the plane was clean two days prior. Valens wonders if someone put sugar in Edna's fuel tank. They figure sugar was hard to come by due to the war rationing. Stillman learns that Frank James ordered sugar before the accident.

Meanwhile, Moe meets with Rush in her car. She tells him to back off and readies her gun. Moe tells her the more she pushes, the more she will lose.

Vera reports that he believes Lynn was flying north for an official assignment. Stillman meets with Frank and tells him they know he was forced to be an instructor instead of fighting on the line. He asks him if he was trying to scare the WASP pilots into quitting. Rush shows Frank a log showing he bought a large amount of sugar that could have been used to sabotage Edna's flight. Frank denies ordering the sugar. He remembers when Lynn told him she checked the maintenance log and saw the plane was clean. Lynn informed him she saw Herbert at the hanger and suspects he sabotaged her plane. Frank told her he doesn't want to bust his own brother. He said even though he loved her, accidents happen. Frank says he confronted Herbert about the sabotage, but he denied it.

The detectives tell Herbert that Frank is going to be arrested. Herbert confesses he sabotaged Edna's plane, but thought she would bail out. He explains he never meant to hurt anyone. He says he begged Lynn not to report him, but she said she already filed a report. He waited for the MP's to arrest him, but they never came.

The detectives bring in Iris and tell her they know the report Lynn filed never went past her to her superior officers. Rush tells Iris she read her book and knows she believes Lynn was going to fly to meet her boyfriend. Rush is skeptical since it appears Lynn was on route to a nearby airforce base. Rush says she saw her flight schedule which was filed only a few days after Lynn disappeared. Rush suspects Iris knew Lynn was never coming back since Lynn was not on the schedule. Iris remembers when Lynn figured she didn't file the report. Iris told her if the military found out that men were sabotaging them, they would shut them down. Lynn told Iris the truth must be heard since Edna was murdered. Iris told Lynn she was right and ordered her to fly north to inform a General about what happened. After Lynn went to pack, Iris sabotaged her plane. Iris and Herbert are arrested for murder.
