If the start of the film is a bit tedious it does pick up noticeably when we actually see a zeppelin! The expedition runs into trouble and is lost (hence the title) after it crashes into the ice. America, including Miriam listens avidly at the radio for progress of the rescue... but for whom is she most anxious to hear about?
Although not perfect by any means - the opening twenty minutes drag awfully and the film suffers from the usual stilted dialogue of early talkies especially from Cortez though he would soon master sound films - the film is a solid aerial adventure with good special effects. Nice twist at the end too.
