How does Anne Trent die in the novel, U.S.A.?

Anne falls in love with Dick Savage; they have an affair, and she gets pregnant. She wants to keep the baby and to marry Savage, but he's not interested and urges her to have an abortion. Heartbroken, she decides to die. She meets an airman, gets drunk with him, and talks him into taking her flying and doing loopthe- loops. Of course, he's not sober enough to do this safely, and the plane crashes, killing them both.
