Most of those applications were dreamt of, and to some degree implemented, long before google glass. The F-35 utilizes a "smart helmet" (or whatever the thing is called) that permits the pilot to look through the aircraft in any direction they can turn their head. Cars and aircraft have utilized HUDs for many years (not worn, but that's a limitation of technology at the time). Battlefield combat in Soldier 2.0 and similar initiatives long predates the Google Glass project.

These aren't applications discovered with it, these are applications potentially implemented with it or similar tech. I'd wager that video games (primarily the real-time sort) have given more inspiration for applications of AR and proper worn HUDs than Google Glass itself produced.
