My grandfather's wreck

Saturday I had to go over to my grandparents trailer to get my grandmother's motorized wheelchair out of the back of my grandfather's truck. My half-brother went with me nad we wrestled then unwieldy thing up 6 stairs and into the trailer... I'm sure glad we did, Monday my grandfather was driving and someone came out of an intersection "lost control" they claim" and absolutely slammed into the back end of the truck. The truck rolled and my the cab crushed down around my grandfather. It took emergency services over a half hour to cut him out. He was quite lucky, he only has some serious roadrash on his head, shoulders etc and had some glass they had to dig out of him.
