A method of training a plurality of pilots, each in a separate real aircraft, includes providing a head mounted see-through computer display (HMD) to each of the plurality of pilots such that each of the plurality of pilots are enabled to view a common virtual environment with computer rendered training content, tracking a location, attitude and speed of each of the separate real aircraft, positioning the computer rendered training content at a geospatial location within a visual range of each of the plurality of pilots and presenting the computer rendered training content to the HMD of each of the plurality of pilots, wherein the presentation in each individual HMD is dependent on an alignment of each respective HMD and the computer rendered content geospatial location.
