Abstract: A method and a portable inhibitor which will focus a blast from an improvised explosive device aboard a pressurized aircraft in flight by using current Federal Aviation Administration least risk bomb location (LRBL) procedures. The portable LRBL is created using a collection of inflatable cubes which interlock with one another. The cubes are made from a resilient inner bladder which is filled with halon gas or other such fire retardant gas. The outer shell is made from ballistic material such as Kevlar. The portable LRBL is stored in a deflated mode. In order for the device to be used, it must be inflated. Once inflated, the cubes will be assembled and placed at a pre-determined position on the aircraft. This location will vary depending on the type and manufacturer of the aircraft. Once the cubes are connected and stacked, the structure will provide multi layered protection to the aircraft and passengers.
