I have been following this closely. Thought about dusting off the old development glasses and trying something like this a while back. Glad to see you are making progress. One additional thought I had, when I was pondering such a mod, was to have a rescue Heli land on the scene and perform the same steps as would the paramedic on the ground or have the ambulance pick the person and drive to the waiting Helicopter (Somewhere safe where it could land) then off to hospital. Keep up the struggle. :)
