Study for "Dropping supplies by air"

Pencil study for watercolour drawing "Dropping supplies by air, Bougainville", featuring four servicemen preparing for an air-drop in front of the open side door of the plane. The supply containers, called "storepedoes", were dropped out of the plane into jungle clearings. None of the crew wear safety harnesses, and there were instances where some dispatchers followed the supplies out the door. This sketch was made shortly after the artist experienced a close call himself. He describes how the plane "fell into an air pocket and the left wing dropped just as I lifted and heaved the rear end of a large and heavy storepedo. As the plane tipped in the direction I was heaving I was thrown forward off balance. I tripped over the box and followed the storepedo out of the open door, luckily not all the way."
