4. and Lighter Than Air) is a 1945 World War II film about U.S. Navy blimps directed by William A. Wellman and starring Wallace Beery, Tom Drake, Jan Clayton and James Gleason.

[1]During World War II, Chief Aviation Pilot Ned Trumpet (Wallace Beery) is the commander of a U.S. Navy K class blimp at Lakehurst, New Jersey naval base.

By chance, Trumpet soon meets Jess Weaver (Tom Drake), a young disabled man, arranging for an operation to fix his legs, injured in a riding accident.

With the airship punctured and losing helium, the crew jettison as much as they can to gain altitude; when that is not enough to reach clouds to hide in, both Trumpet and Shannon parachute out.

As a rough-hewn, golden-hearted chief petty officer in the Navy's blimp service, he is scarcely different from Beery the erstwhile marine, gob, etc.

Paris wrote, the film "is something of a throwback to the melodramatic style of the pre-war years and is strangely at odds with the realistic and sombre mood of Wing and a Prayer.
