 In February 1942, the RAAF began experimenting with skip bombing, an anti-shipping technique used by the British and Germans.Flying only a few dozen feet above the sea toward their targets, aircraft would release their bombs, which would then, ideally, ricochet across the surface of the water and explode at the side of the target ship, under it, or just over it.A similar technique was mast-height bombing, in which bombers would approach the target at low altitude, , at about , and then drop down to mast height, about from the target.
