A hemisphere screen for training air gunners at No. 2 Bombing and Gunnery School RCAF (Royal Canadian Air Force), Empire Air Training Scheme, Mossbank, Saskatchewan, Canada, 1944. Moving images of fighter aircraft were projected across the concave surface of the screen as the trainee gunner sat in a mock turret and projected a beam of light, simulating the spread of his fire at the target. [R Malcolm Warner, 1944, watercolour and brush and ink heightened with white over pencil on wove paper, 37.6 x 55.5 cm, AWM ART24100]
