Query: Flawed memoir has anachronisms and lacks credibility

An interesting memoir, but has a serious problem. The author mentions that her Soviet Partisan unit was subjected to a German helicopter attack in 1944. The Germans did not have any helicopters in WWII, and neither did any other country. They did have ground attack airplanes, but the book describes a helicopter attack. There is either a credibility problem with this account, or some type of translation/linguistic error. The publisher should have caught this.
