How did air power influence the Kokoda Campaign?  We review the employment of air power and compare it with the Milne Bay operation, where Air Power's effect was described as 'decisive' by both MAJGEN Clowes and LTGEN Rowell. The episode picks up the story with the elevation of Les Jackson to CO of No 75 Squadron after the death of his brother, John.  We discuss the importance of training pilots for the responsibilities for Squadron Command and the requirement for a panel of potential candidates, before looking at the Battle of Milne Bay. This is Part 18 of our series looking at the Kokoda Campaign, focusing on the combat performance of battalions on the Kokoda Track and the fourth and final episode as we look at Air Power, RAAF Leadership and doctrine development during the Kokoda Campaign.  Check out the  show notes for the podcast for all of the information that we cover in this episode as well as the images and other details that didn't make it into the podcast.
