Daisy Whitman was a vertibird pilot in the Enclave, she often flew Captain Judah Kreger's squad on missions; she flew 71 missions for the Enclave at the cost of one vertibird, which crashed near Klamath after a rotor malfunction. This is the crashed vertibird seen in Fallout 2, and is where Lily Bowen found the parts for her vertibird blade sword. She loved flying, and often took a scenic route back to Navarro so she could stay airborne longer; it gave her a sense of freedom, she could fly to "anywhere and everywhere", limited only by her fuel supply.
Some time after the destruction of the Enclave Oil Rig, the NCR attacked Navarro, and she, the squad, Arcade Gannon's mother and a young Arcade Gannon fled south into the NCR. They continued to flee east as Enclave personnel trying to integrate into the NCR were being found. She and the squad eventually settled in the Mojave Wasteland and went their separate ways. She still longs to fly, and settled in the Dino Dee-lite Motel in Novac, because of the nearby REPCONN Test Site in the hopes that scavenging rocket parts would be something similar to flying.
