Dr. Ronald Evans is a mathematician who joined British Aerospace, or BAe, in 1978 as an expert in fluid mechanics.

The BAE gravity study began with his investigation of gravity as a possible disruptive technology. The study eventually became Project Greenglow, and it collected a group of BAE engineers interested in the idea of a breakthrough in gravitational physics.

Project Greenglow, under the leadership of Dr. Evans, is generally recognized as the most rigorous pursuit of gravity modification and advanced propulsion research performed in the United Kingdom.
