White is famous for her role opposite William Shatner in the Twlight Zone episode "Nightmare at 20,000 Feet." Shatner played a man recently released from a sanitarium following a mental breakdown on an airplane. As he and his wife, played by White, fly home, Shatner's character grows increasingly upset as he witnesses a "gremlin" tampering with the wing that only he can see. As Shatner's mental state crumbles, White's character struggles to keep him composed.
She is survived by several nieces and nephews.
