I hope it's not a spoiler but the villain of the piece is the chiffon pumpkin pie. A good old fashioned airliner in distress story with the pilot and co-pilot incapacitated and a burnt out professional placed under stress to save the day... In this case the burnt out professional is a doctor who must treat the sick men as well as deliver a baby - not a traumatized pilot who's still not "over Macho Grande".
Good performances and generally believable technical dialog improve matters. Pretty good if you can forgive the overly familiar plot.
