El copiloto y el ingeniero de un avión de pasajeros luchan por mantener el avión en el aire hasta que pueda llegar a un aeródromo abierto después de que un asesino a bordo del avión dispara un arma contra el motor y el piloto del avión.
Tough, but troubled Captain Pete Douglass (the always dependable David Janssen in sturdy stalwart form) has his hands full dealing with both a fierce snow storm and dangerous convict Greco (delightfully overplayed with lip-smacking maniacal relish by Marjoe Gortner), who's being transported to prison on board Douglass's passenger jet.Director Robert Butler keeps the entertaining story moving along at a brisk pace and generates a good deal of tension.
If you are a fan of "Zero Hour" "Airport" and "Skyjacked" then you will probably be mildly entertained by "Mayday at 40,000 Fee!" TV movie "Mayday" doesn't quite take off like the theatrical distressed airplane films.
Routine disaster movie but with a knockout cast.With a couple of exceptions, I know the whole cast of this film from other productions of the 60s or 70s - be it be QM's The Fugitive or Earthquake or whatever!
