An American B-25D bomber flies at minimum altitude, probably during training/practice of 'low-level attack techniques.' Note the triangular peak just in front of the aircraft. This is probably piled up dirt and sand bags, used as the 'target' to learn and practice, especially for 'skip bombing'.

B-25 pilots of the Tenth Air Force (341st Bomb Group) and Chinese-American Composite Wing (1st Bomb Group) were trained in 'skip bombing' in India during 1943 and 1944.
