Factual error: While watching the Sonja Henie movie "Sun Valley Serenade" Colonel Potter says at one point of the movie "This is supposed to be where she does a triple axel and ends up in a split." Then he has to leave and says "Now I'll never get to see it." He wouldn't be able to see it until 1989 when Midori Ito from Japan was the first woman to complete a triple axel in competition, Tonya Harding was the 2nd woman to complete one and the only American woman. And I doubt Sonja Henie ever did anything as complicated as a triple axel even with her 3 Olympic Gold Medals.
Factual error: As Hawkeye performs CPR on the hypothermic soldier, he pumps his arms from his ellbows. CPR is done by keeping the arms stiff and pumping with the whole upper body. Hawkeye as a surgeon would know that. Fun Fact: You can perform CPR one-handed in a pinch, but only as long as you keep your arms stiff.
