Season 81/8/2007

A timer counts down onscreen as B.J., Hawkeye, and the rest of the 4077th race to save the life of a GI who needs an aorta transplant. The doctors know how much time they have before it is too late, and so do the viewers as the seconds tick away. Medically accurate, grippingly real, this is truly one of the series most riveting episodes.
