"Slip bomber" is a specific term used to describe a type of aircraft drop in bombing technique, where the aircraft approaches the target at a low altitude and then "slips" or drops altitude suddenly to release the bombs. In terms of synonyms, the technique can also be referred to as "skip bombing" or "glide bombing". These terms indicate the same concept of approaching a target at a low altitude and using the aircraft's momentum to drop bombs accurately on the intended target. While the terminology may differ, the goals and methods of these techniques remain largely the same, varied only by the individual aircraft and altitude capabilities.
