As far as I know, Sunseeker isn't "business". It's a one-off and a research aircraft which has demonstrated Raymond's talents. I think he makes a living as a consultant for the E-propelled aviation business and probably also for civilian and military drones. He's a very busy man and one who very carefully manages his schedule.

and you may contact Irena and Eric Raymond through that page.

I had the privilege to fly with Eric in the Sunseeker Duo, and that will remain in my memory as one of the most exhilarating experiences I had in aviation.
