About twenty minutes into the film, an airfield emergency is declared with an aircraft coming in "on two engines". There then follows a polyglot of stock footage showing four four-engine B-24 Liberators, all with all engines turning, wartime-footage of a B-25 Mitchell twin-engine bomber crash-landing, followed by a flight of four four-engine B-17 Flying Fortresses approaching a field, and then, B-24s rolling out on landing. No attempt was made at matching footage of the aircraft types shown.
