So bad it's good
This film is so awful (in acting, in cogent story line, in stereotype of both American and Russian military officers, and in the complete impossibility of Janet Leigh and John Wayne ever being a couple, that the entire story is "over the top."
American military men with no orders, just "winging it" in the middle of the Cold War, with lines like, "Colonel, I trust ya." Russians speaking reasonably and logically with "American-ski" dissidents, defectors, and spies. Janet Leigh smacking John Wayne around with a Tokarev (?) type pistol way too big for her. Then add notes on a matchbook cover, enough smoking to cause secondary-lung cancer to the entire cast and crew, and an entire array of 50s type furniture in chartreuse and beige with matching limed-oak tables.
HOWEVER, the planes are magnificent, and a reminder of what "seat of the pants" actually meant. This is not slick "Top Gun" ala Tom Cruise, overly dramatic and hyped flying, ‘cause this is 1957. Don't let the silly story line ruin the enjoyment of seeing what we actually flew during the Cold War. The take-offs and landings are poetry.
